CHAPTER-1 ADVANTAGES The Java Ring can be described as stainless-steel diamond ring, 16-millimeters (0. 6 inches) in size that residences a 1-million-transistor processor, called an iButton. The ring has 134 KB of RAM, 32 KB of ROM, a real-time time and a Java online machine, a piece of software that recognizes the Java dialect and translates it pertaining to the customer’s computer system.
For Celebration University, the jewelry have been set to store electronic cash to purchase lunches, quickly unlock doorways, take attendance, store a student’s medical information and allow students to consider books.
All of this information can be stored within the ring’s iButton. Students merely press the signet of their Java Band against the Green Dot receptor, and the program connected to the receptor performs the function which the applet teaches it to. In the future, the Java Band may start your car or truck. Mobile computing can be beginning to break the chains that tie up us to our desks, but many of this mobile devices could be a little awkward to transport around. Within the next age of computing, we will see a great explosion of computer parts across our systems, rather than throughout our personal computers.
Digital rings, designed to health supplement the personal pc, will be the progression in digital technology that makes laptop elements entirely compatible with your form. The Java Engagement ring, first introduced at Java One Meeting, has been examined at Celebration School, a modern K-12 institution just outdoors Orlando, FLORIDA. The jewelry given to college students are programmed with Java applets that communicate with number applications upon networked devices.
Applets happen to be small applications that are designed to be run inside another application. The Java Ring is snapped into a reader, called a Blue Department of transportation receptor, allowing communication between a host program and the Java Ring. [pic] [pic] [pic] Figure you: prototype of stainless steel java ring. CHAPTER-2 HISTORY Throughout summer of 1989, Dallas Semiconductor Corp. created the 1st stainless- stainlesss steel encapsulated memory devices utilizing the Based in dallas Semiconductor 1-Wire communication process.
By 1990, this process had been enhanced and used in a variety of self-contained memory gadgets. Originally called “touch memory” devices, we were holding later renamed “iButtons. inches Packaged just like batteries, iButtons have only a single energetic electrical speak to on the top surface area, with the stainless-steel shell serving as earth. Data may be read from or drafted to the memory serially through a simple and economical RS232C serial port assembler, which as well supplies the power required to carry out the I/O.
The iButton memory could be read or written using a momentary speak to to the “Blue Dot” radio provided by the adapter. You should definitely connected to the dramón port assembler, memory data is taken care of in non-volatile random gain access to memory (NVRAM) by a life time lithium strength supply that will maintain the recollection content no less than 10 years. Unlike electrically erasable programmable read-only memory (EEPROM), the NVRAM iButton storage can be removed and rewritten as often as necessary without deteriorating.
It can also be removed or rewritten at the substantial speeds normal of contributory metal o2 semiconductor (CMOS) memory, lacking the time consuming programming of EEPROM. As their advantages, iButton memory devices have been completely deployed in vast quantities as rugged portable data carriers, typically in tough environmental circumstances. Among the large-scale uses will be as flow fare carriers in Turki, Turkey, as maintenance record carriers within the sides of Ryder pickup trucks, and as mailbox identifiers inside mail storage compartments of the U.
S. Da postagem Service’s outdoor mailboxes. They are put on as diamond earrings by bovine in Canada to support vaccination documents, and they are employed by agricultural employees in many areas as tough substitutes for timecards. The iButton production and its various applications happen to be described by Dallas Semiconductor’s iButton Web site, which is classified by the Resources section. Every iButton product is manufactured with a one of a kind 8-byte serial number and carries a guarantee that no two parts is ever going to have the same quantity.
Among the simplest iButtons are memory products that can carry files and subdirectories and can be read and written just like small floppy disks. Furthermore to these, there are iButtons with password shielded file areas for protection applications, iButtons that depend the number of instances they have been rewritten for securing financial transactions, iButtons with temperature detectors, iButtons with continuously operating date/time clocks, and even iButtons containing highly effective microprocessors. The java engagement ring was first launched in the year 1998, in the java one convention. he diamond ring was developed by the Dalas semiconductor organization. 2 . one particular The da postagem security device For over a decade, Dallas Semiconductor also has been creating, making, and selling a line of highly secure microprocessors that are used in satellite TV descramblers, automatic teller machines, point-of-sale terminals, and also other similar applications requiring cryptographic security and high resistance from attack by simply hackers. The U. T. Postal Service’s (USPS) Data Based Indicia Program Postal Security Device Specification, designed to permit producing of valid U.
H. postage in any LAPTOP OR COMPUTER, provided the first opportunity to combine two areas of expertise when a protect microprocessor was created into a great iButton the resulting product, named the Crypto iButton, combines excessive processor functionality, high-speed cryptographic primitives, and exceptional prevention of physical and cryptographic strike. For example , the top integer do it yourself exponentiation engine can perform 1024-bit modular exponentiations with a 1024-bit exponent in significantly less than a second.
The ability to perform large integer modular exponentiations at high speedis central to RSA encryption, Diffie- Hellman crucial exchange, Digital Signature Common (FIPS 186), and many other modern day cryptographic businesses. An agreement among Dallas Semiconductor and RSA Data Reliability Inc. offers a paid-up license for anyone using the Crypto iButton to perform RSA encryption and digital autographs so that no more licensing with the RSA security technology is essential. High security is provided by the capacity to erase the contents of NVRAM really quickly.
This feature, speedy eroization, is a requirement for substantial security devices that may be exposed to attacks simply by hackers. As a result of its large security, the Crypto iButton is likely to win the FIPS 140-1 security qualification by the National Institute of Standards and Technology (NIST).
While not a Java virtual machine, the E-commerce firmware made for this application had a lot of points of similarity with Java, including an object-oriented design and a byte code interpreter to interpret and execute Based in dallas Semiconductor’s custom-designed E-Commerce Script Language. A compiler was also drafted to make the high-level language manifestation of the Script Language to a byte code form that could be interpreted by the E-Commerce VM.
Although the E-Commerce firmware was intended primarily for the USPS software, the firmware supports a variety of general digital commerce versions that are suitable for many different applications. The E-Commerce firmware also supports cryptographic protocols for secure information exchange such as the Simple Key-Management for Internet Protocol (SKIP) developed by Sunshine Microsystems Inc. The Web commerce iButton as well as the SDK intended for programming this are explained in detail within the Crypto iButton home page. CHAPTER-3 COMPONENTS The main components of the java band are pursuing: – JAVA VIRTUAL MACHINE(JVM) o 134KB OF MEMORY o 32KB OF RAM o REAL TIME CLOCK u IBUTTON um BLUE APPEAR IN RECEPTOR several. 1 . JAVA VIRUAL EQUIPMENT Java engagement ring is developed with java application plan and applets that communicate with the web host application for the networked system. Applets are the small software that is designed to managed with the one more application program. The java virtual machine is the piece of software that recognizes the java language and translate the byte code, which is used by system which can be connected to the java ring via ring reader.
At Celebration School, the rings have been completely programmed to maintain electronic funds to pay for en-cas, automatically uncover doors, consider attendance, store a present student’s medical information and allow college students to check out catalogs. All of this information is kept on the ring’s iButton. Pupils simply press the label of their Java Ring against the Blue Dot receptor, as well as the system coupled to the receptor performs the function that the applet instructs that to. Down the road, the Java Ring may start your car.
Traveling with a laptop is beginning break the chains that tie all of us to our desks, but many of today’s mobile phones can still become a bit cumbersome to carry around. In the next regarding computing, we will see an huge increase of computer system parts around our bodies, rather than across each of our desktops. Digital jewelry, designed to supplement the individual computer, will be the evolution in digital technology that makes computer components entirely compatible with the human kind. 3. 2 . RAM Java ring consists of 134kb of nonvolatile unique access memory.
Program and data can be stored in this kind of nonvolatile random access memory. This non-volatile random access memory gives high read/write speed and also provides mood resistance through instantaneous cleaning of all recollection when tempering is detected. This process is known as rapid zeroization. The NVRAM iButton memory can be deleted or rewritten as often as required without wearing out. High reliability is offered by the ability to erase the content of NVRAM really quickly.
The Crypto iButton also offers an excellent hardware platform for executing Java because it utilizes NVRAM pertaining to program and data storage area. With six kilobytes of existing NVRAM and the probability of expand the NVRAM capacity to as much as 128 kilobytes in the existing iButton form factor, the Crypto iButton can execute Java using a relatively significant Java stack situated in NVRAM. This memory acts as standard high-speed MEMORY when the cpu is performing, and the li (symbol) energy preserves the complete state of the machine while the Java Ring is usually disconnected in the reader.
There exists therefore simply no requirement to cope with persistent items in a special way , objects continue or certainly not depending on their very own scope and so the programmer has complete control of object persistence. As in normal Java, the Java iButton contains a garbage collector that gathers any things that are away of range and recycles the memory space for long term use. Applets can be crammed and not loaded from the Java iButton as frequently as needed. All the applets currently packed in a Java iButton will be effectively carrying out at absolutely no speed whenever the iButton is not in contact with a Blue Department of transportation receptor.
While the Java Card installment payments on your 0 requirements was recommended, Dallas Semiconductor became a JavaSoft licensee. The agreement called for the development of a Java Card 2 . 0 implementation and also for the design of “plus portions” that take advantage of the unique capabilities afforded by the Crypto iButtons NVRAM, such as the ability to support a genuine Java bunch and waste collection. With the help of the constantly running lithium-powered time-of day clock plus the high-speed, large-integer modular exponentiation engine. a few. 3. ROM The java ring is made up of 32kb of ROM.
A particular kind of main system called Internet commerce. operating system which is based on java and JVM is kept in the RANGE OF MOTION. This main system handles every one of the operation which can be happening in the iButton. It is stored in ROM because it is not really supposed to be altered by the end user. The Crypto iButton components platform presents a unique pair of special features expressly designed to prevent non-public keys and also other confidential details from becoming available to cyber-terrorist. Figure reveals a fine detail of the internal construction of the Crypto iButton.
The si die that contain the processor, ROM, and NVRAM storage is metallurgically bonded to the barrier substrate through which almost all electrical contacts are made. This barrier base and the triple-layer metal development techniques used in the silicon fabrication efficiently deny entry to the data stored in the NVRAM. If virtually any attempt is made to penetrate these kinds of barriers, the NVRAM data is right away erased. This kind of construction strategy and the utilization of NVRAM for the storage area of private tips and other confidential data supplies a much higher degree of data reliability than that afforded simply by EEPROM storage.
The fact which the communication path between the Crypto iButton as well as the outside globe is limited to a single data line delivers additional security against equipment attacks by simply limiting the range of signs accessible for the hacker. Additionally , the cpu itself is usually driven by an unstabilized ring oscillator operating more than a range of 10 to 20 megahertz, so that the time clock frequency of the processor is definitely not regular and cannot be determined by exterior means. This kind of differs through the design of alternate devices when the processor clock signal is injected by reader and is therefore accurately determined by the host cpu.
External control over the clock supplies a valuable application to hackers, since they can easily repetitively pattern such a processor to the same point in its execution simply by making use of the same range of clock cycles. Control of the time also provides a means to cause a calculations error and thereby attain information that could ultimately uncover secret security keys. A 32-kilohertz ravenscroft oscillator is employed in the Java iButton to work the time-of-day clock by a constant and well-controlled frequency that is in addition to the processor time. 3. four. REAL TIME TIME CLOCK
In the java ring real-time clock provides exact time of the day. The simultaneity clock consistently running about more than a decade by the energy provided the lithium back-up. In addition , the processor alone is powered by a great unstabilized ring oscillator functioning over a array of 10 to twenty megahertz, in order that the clock frequency of the cpu is certainly not constant and cannot be dependant upon external means. This differs from the type of alternative products in which the processor chip clock transmission is shot by the visitor and is as a result exactly dependant on the host processor.
Exterior control of the clock provides a useful tool to hackers, given that they can repetitively cycle this sort of a processor chip to the same point in its execution simply by applying precisely the same number of clock cycles. Power over the clock likewise affords a quick way to induce a calculation mistake and thus obtain info that can eventually reveal magic formula encryption important factors. A 32-kilohertz crystal oscillator is used inside the Java iButton to operate the time-of-day time clock at a constant and well-controlled frequency that is certainly independent of the cpu clock.
In addition , the cpu itself is driven simply by an unstabilized ring oscillator operating over the range of 10 to 20 megahertz, so that the clock frequency in the processor is not regular and can not be determined by exterior means. This kind of differs from your design of alternate devices where the processor time signal is definitely injected by reader and is also therefore accurately determined by the host cpu. External power over the clock offers a valuable device to hackers, since they may repetitively cycle such a processor for the same justification in its execution simply by applying the same quantity of clock periods.
Control of the clock also affords a means to induce a calculation error and thereby obtain information which could ultimately reveal secret security keys. A 32-kilohertz crystal oscillator is used in the Java iButton to control the time-of-day clock for a constant and well-controlled rate of recurrence that is in addition to the processor time. 3. 5. IButton [pic] Figure: composition of the iButton The jewel of the java ring is the java iButton. It contains normally the one million receptor processor one chip dependable microprocessor with powerful java virtual machine(JVM) housed in rugged and secure stainless case.
The Crypto iButton hardware system offers an exceptional set of particular features expressly designed to prevent private important factors and other secret information from becoming open to hackers. Figure 1 shows a detail of the internal construction with the Crypto iButton. The silicon die that contains the processor, ROM, and NVRAM memory is metallurgically bonded to the barrier base through which almost all electrical connections are made. This barrier base and the triple-layer metal structure techniques employed in the silicon fabrication efficiently deny use of the data kept in the NVRAM.
If any kind of attempt was created to penetrate these types of barriers, the NVRAM data is immediately erased. This kind of construction approach and the make use of NVRAM for the storage of private secrets and other private data provides a much higher degree of data secureness than that afforded simply by EEPROM storage. The fact that the communication way between the Crypto iButton plus the outside universe is limited to a single info line gives additional security against hardware attacks by simply limiting kids of signs accessible towards the hacker.
In addition , the processor chip itself is definitely driven simply by an unstabilized ring oscillator operating over the range of 12 to 20 megahertz, so that the time clock frequency with the processor is usually not continuous and cannot be determined by exterior means. This kind of differs from your design of alternate devices where the processor time clock signal is definitely injected by the reader and is also therefore accurately determined by the host cpu. External control over the clock provides a valuable device to cyber-terrorist, since they can repetitively routine such a processor to the same point in its execution simply by making use of the same quantity of clock periods.
Control of the clock also provides a means to induce a calculation error and thereby attain information that can ultimately reveal secret encryption keys. A 32-kilohertz ravenscroft oscillator is employed in the Java iButton to control the time-of-day clock for a constant and well-controlled regularity that is independent of the processor clock. It is actually called feel memory equipment they were after renamed as “iButtons packaged like batteries. IButton have got only just one active electric contact on the top surface device stainless steel cover serving while ground.
Just about every iButton product is manufactured with unique almost 8 byte dramón number and carries a warranty that zero two IButtons have same number. Among the simplest iButton are storage devices which could hold documents and web directories that can be examine and created like small floppy hard disk drives. An iButton is a microchip similar to those used in smart card but housed in a round stainless steel switch of seventeen. 35mm by 3. 1mm , 5. 89mm in proportions (depending around the function). The iButton was invented and is still created exclusively by simply Dallas semiconductor mainly for applications in harsh and requiring environments.
Like a smart card, a great iButton would not have an inside power supply. It requires connection to a visitor (known as being a Blue Appear in Receptor) in order to be supplied with electrical power and to obtain input and send end result. Unlike some smart greeting cards, there are currently no contactless iButtons: they need physical exposure to a reader to function. You will discover iButtons that measure temperature (for foodstuff storage and transport), have an electronic IDENTITY (for physical access to buildings), and retail store e-cash (for purchases both in stores and via the web). For e-commerce applications, the iButton can support Java Card 2 . /OpenCard standard furthermore to amazing software. iButtons have an benefit over conventional smart greeting cards in term of strength and longevity. The stainless-steel casing provides iButton a far greater ability to make it through in a range of temperature ranges , every versions will be functional by -40 C to +70 C , and in a much harsher array of environments (such as contact with salt water and long term exposure to physical impacts) compared to the plastic smart card. For web commerce and personal IDENTITY usage, iButtons can be attached to a range of personal accessories: view, ring, crucial chain, or dog tag.
Among the key successes to get the iButton have been its use in Turkey as an epurse for the mass transit program, in Argentina and Brazil for auto parking meters, and in usa as Green Mailbox attachments that improve postal productivity. [pic] Figures 3. a few. 2: various kinds of iButtons available in the market 3. 6th. BLUE DEPARTMENT OF TRANSPORTATION RECEPTOR The read/write operation in the java ring is performed by the blue dot receptor provided by the RS232 dramón port joindre. The DS1402D-DR8 is a portion of the DS1402 series.
It is a 1-Wire network cable designed to hook up any serial or USB 1-Wire dock adapter with a RJ11 jack with approximately two iButtons simultaneously.

To get hands-free operation the iButton can be clicked into the Blue Dot and remain presently there. Each radio contains two Blue Dots to accommodate instances where multiple iButtons are required for a purchase. A provider’s policy may possibly, for example , need both a worker and a supervisor to authenticate usage of sensitive details stored on a network server. [pic] [pic]
Figures3. 6th: different types of green dot receptor in the market. CHAPTER-4 WORKING Physique 4: just how java band is used to spread out the door As java ring is designed with the applets and the programming is done in accordance to our application and this will certainly specific to get the specific customer. All information from the user is definitely stored in the java engagement ring. Figure some: how java ring is utilized to open the doorway User basically has to press the label of the java ring resistant to the blue us dot receptor and the system connected to the receptor functions the function that the applets instruct that to. ava ring has got the user profile plus the same profile is present inside the door embedded system as well, when the customer press the signet from the java diamond ring against the java ring target audience which is embedded at the deal with of the door the data is transferred from your ring to door system. if the profile is traditional means end user is authentic to open the doorway the applets president in the ring advise the door to open. Information is definitely transferred among iButton and a COMPUTER with a temporary contact, at up to 142K pieces per second. To do that one particular presses iButton to the Blue Dot radio, a $15 pipeline in PC.
The Blue Dot sticks to any convenient spot on the front of any PC and is cabled towards the serial or parallel interface in the backside. According to the Dallas Superconductor’s info, over forty one million iButtons are currently in circulation. List of the major users include the U. S. Mailbox, entire pickup truck fleet when you have iButtons that track automobile maintenance, People of Turki, Turkey, who have store digital cash in the iButton, making use of the device like a small alter purse prove mass flow system. it absolutely was also stated that the U. S.
Da postagem service provides approved the cryptographic iButton as a Da postagem Security Device to be used in its PERSONAL COMPUTER Postage software that allows visitors to download nearly all off the Internet and produce it off their own Machines Since all their introduction, iButton memory products have been deployed in great quantities as rugged lightweight data providers, often in harsh environmental conditions. Among the large-scale uses are since transit do carriers in Istanbul, Turkey, as repair record carriers on the attributes of Ryder trucks, and as mailbox verifications inside the email compartments from the U. H. Postal Service’s outdoor mailboxes.
They are worn as earrings simply by cows canada to hold vaccination records, plus they are used by gardening workers in several areas as rugged substitutes for timecards. The iButton product line and its particular many applications are defined at Based in dallas Semiconductor’s iButton Web site, which can be listed in the time section. Just about every iButton method manufactured using a unique 8-byte serial quantity and posesses guarantee that zero two parts will ever have the same number. Among the simplest iButtons are recollection devices that could hold data and subdirectories and can be go through and created like tiny floppy hard disk drives.
In addition to, there are iButtons with password-protected file areas for security applications, iButtons that depend the number of instances they have been rewritten for obtaining financial orders, iButtons with temperature receptors, iButtons with continuously operating date/time lighting, and even iButtons containing strong microprocessors. Info is transmitted between iButton and a PC having a momentary get in touch with, at up to 142K bits every second. To accomplish this one squeezes iButton towards the Blue Dot receptor, a $15 pipeline into PC.
The Blue Dot sticks to any practical spot on front side of a COMPUTER and is cabled to the serial or parallel port in the back. According to the Dallas Superconductor’s information, over 41 mil iButtons are in circulation. List of the users include the U. S i9000. Post Office, whole truck navy fitted with iButtons that monitor vehicle repair, Citizens of Istanbul, Chicken, who retail outlet digital cash in the iButton, using the gadget as a small change purse on their mass transit system. it was likewise said that the U. H.
Postal service has permitted the cryptographic iButton being a Postal Security Device to become used in their PC Nearly all program which allows individuals to download postage from the Internet and print that from. PHASE 5 SECURENESS The java ring supplies very high amount of security for the confidential data that is trapped in the NVRAM memory. The barrier base and the triple layer approach effectively reject access the unauthorized access to the NVRAM confidential data. In the worst case if any not authorized access permeates the obstacle the security processor detects it and instantly the data which is written inside the NVRAM.
The Crypto iButton hardware program offers a unique set of particular features expressly designed to stop private secrets and other secret information coming from becoming open to hackers. Number shows a detail of the internal construction of the Crypto iButton. The silicon die containing the processor, ROM, and NVRAM memory is definitely metallurgically attached to the obstacle substrate whereby all power contacts are made. This obstacle substrate plus the triple-layer metal construction tactics employed in the silicon architecture effectively refuse access to the data stored in the NVRAM.
If any strive is made to permeate these barriers, the NVRAM data is definitely immediately removed. This development technique as well as the use of NVRAM for the storage of personal keys and also other confidential info provides a higher degree of info security than that afforded by EEPROM memory. The fact that the communication path involving the Crypto iButton and the outside world is restricted to a sole data series provides added security against hardware disorders by restricting the range of signals attainable to the hacker.
In addition , the processor itself is influenced by a great unstabilized diamond ring oscillator working over a variety of 10 to twenty megahertz, so that the clock frequency of the processor is certainly not constant and cannot be determined by external means. This may differ from the style of alternative equipment in which the processor clock sign is inserted by the reader and is as a result exactly based on the number processor. xternal control of the time provides a beneficial tool to hackers, simply because they can over and over again cycle this kind of a cpu to the same point in the execution by simply applying a similar number of time clock cycles.
Charge of the clock also affords a quick way to induce a calculation problem and thereby obtain Info that can ultimately reveal top secret encryption secrets. A 32-kilohertz crystal oscillator is used in the Java iButton to operate the time-of-day time clock at a consistent and well-controlled frequency that may be independent of the cpu clock. your five. 1 .
