The JavaRing is a tiny wearable computer with 6 kilobytes of RAM. Six K may not sound like much, but it is 20 percent more memory than the first computer I ever used (back in high school in 1973): an ancient (even at the time) Danish second-generation computer called Gier or A Java Ring is a finger ring that contains a small microprocessor with built-in
capabilities for the user, a sort of smart card that is wearable on a finger. Sun
Microsystemsâ„¢s Java Ring was introduced at their Java One Conference in 1998
and, instead of a gemstone, contained an inexpensive microprocessor in a stainlesssteel iButton running a Java virtual machine and preloaded with applets (little application programs). The rings were built by Dallas Semiconductor.

Workstations at the conference had "ring readers" installed on them that
downloaded information about the user from the conference registration system. This information was then used to enable a number of personalized services. For example, a robotic machine made coffee according to user preferences, which it downloaded when they snapped the ring into another "ring reader."

The Java Ring is an extremely secure Java-powered electronic token with a
continuously running, unalterable real-time clock and rugged packaging, suitable for many applications. The jewel of the Java Ring is the Java iButton -- a onemillion transistor, single chip trusted microcomputer with a powerful Java Virtual Machine (JVM) housed in a rugged and secure stainless-steel case.

JAVA RING

Abstract

Dallas Semiconductor has developed a new Java-based, computerized ring that will automatically unlock doors and log on to computers. This java based technique overcomes the deficiencies of the secret password. A Java Ring is a finger ring that contains a small microprocessor which runs JVM and is preloaded with applets. The jewel of Java Ring is Java iButton, which is a microchip enclosed in a secure package. There are many technologies similar to iButton. But there is no match for this technology. A Java Ring goes beyond a traditional smart card by providing real memory, more power, and a capacity for dynamic programming. iButtons have an advantage over smart cards in term of durability and longevity. There are different kinds of iButtons of which cryptographic iButtons require a special mention. Information is transferred between iButton and PC by means of blue dot receptor. A layer of software called TMEX is needed to interface iButtons to PCs and produce the desired information in the desired format. They find much applications in authentication and auditing trails. With a significant market penetration of 20 billion iButtons, we can expect an exponential growth in this technology. These devices will surely revolutionize the way we look at future.

INTRODUCTION

T seems that everything we access today is under lock and key. Even the devices we use are protected by passwords. It can be frustrating trying to keep with all of the passwords and keys needed to access any door or computer program. Dallas Semiconductor is developing a new Java-based, computerized ring that will automatically unlock doors and log on to computers.This mobile computer can become even more secure. You can keep the iButton with you wherever you go by wearing it as a closely guarded accessory - a watch, a key chain, a wallet, a ring - something you have spend your entire life practising how not to lose. Here are a few reasons why you might want to wear the iButton in the accessory that best fits your life style.

JAVA RING

A Java Ring is a finger ring that contains a small microprocessor with built-in capabilities for the user, a sort of smart card that is wearable on a finger. Sun Microsystem's Java Ring was introduced at their Java One Conference in 1998 and, instead of a gemstone, contained an inexpensive microprocessor in a stainless-steel iButton running a Java virtual machine and preloaded with applets (little application programs). The rings were built by Dallas Semiconductor.
Workstations at the conference had "ring readers" installed on them that downloaded information about the user from the conference registration system. This information was then used to enable a number of personalized services. For example, a robotic machine made coffee according to user preferences, which it downloaded when they snapped the ring into another "ring reader."
Although Java Rings aren't widely used yet, such rings or similar devices could have a number of real-world applications, such as starting your car and having all your vehicle's components (such as the seat, mirrors, and radio selections) automatically adjust to your preferences.

iBUTTON

An iButton is a microchip similar to those used in a smart card but housed in a round stainless steel button of 17.35 mm x 3.1 mm - 5.89 mm in size (depending on the function). The iButton was invented and is still manufacturedm exclusively by the Dallas Semiconductor mainly for applications in harsh and demanding environments.
A Java Ring--and any related device that houses an iButton with a Java Virtual Machine--goes beyond a traditional smart card by providing real memory, more power, and a capacity for dynamic programming. On top of these features, the ring provides a rugged environment, wear-tested for 10-year durability. You can drop it on the floor, step on it, forget to take it off while swimming and the data remains safe inside. Today iButtons are primarily used for authentication and auditing types of applications. Since they can store data, have a clock for time-stamping, and support for encryption and authentication, they are ideal for audit trails

JAVA- POWERED CRYPTOGRAPHIC iBUTTON

The Crypto iButton, combines high processor performance, high-speed cryptographic primitives, and
exceptional protection against physical and cryptographic attack. For example, the large integer modular 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 speed is central to RSA encryption, Diffie-Hellman key exchange, Digital Signature Standard (FIPS 186), and many other modern cryptographic operations.
The U.S. Postal Service's (USPS) Information Based Indicia Program Postal Security Device Specification, intended to permit printing of valid U.S. postage on any PC, provided the first opportunity to combine two areas of expertise when a secure microprocessor was designed into an iButton, resulting in crypto iButton.

CONCLUSION

Dallas Semiconductor has produced more than 20 million physically-secure memories and computers with
hard-shell packaging optimized for personal possession. The Java iButton, therefore, is simply the latest and most complex descendant of a long line of products that have proven themselves to be highly successful in the marketplace. With its stainless steel armor, it offers the most durable packaging for a class of products that likely will suffer heavy use and abuse as personal possessions. The iButton form factor permits attachment to a wide variety of personal accessories that includes rings, watchbands, keyfobs, wallets, bracelets, and necklaces, so the user can select a variation that suits his or her lifestyle.
