JAVA VIRUAL MACHINE
Java ring is
programmed with java application program and applets that communicate with the host
application on the networked system. Applets are the small application that is
designed to run on the another application system. The java virtual machine is the
piece of software that recognizes the java language and translate the byte code
,which is used by the system which is connected to the java ring via ring reader.
At Celebration
School, the rings have been programmed to store electronic cash to pay for lunches,
automatically unlock doors, take attendance, store a student's medical information
and allow students to check out books. All of this information is stored on the
ring's iButton. Students simply press the signet of their Java Ring against the
Blue Dot receptor, and the system connected to the receptor performs the function
that the applet instructs it to. In the future, the Java Ring may start your car.
Mobile computing
is beginning to break the chains that tie us to our desks, but many of today's mobile
devices can still be a bit awkward to carry around. In the next age of computing,
we will see an explosion of computer parts across our bodies, rather than across
our desktops. Digital jewelry, designed to supplement the personal computer, will
be the evolution in digital technology that makes computer elements entirely compatible
with the human form.
RAM
Java ring contains
134kb of non-volatile random access memory. Program and data is stored in this non-volatile
random access memory .This non-volatile random access memory offers high read/write
speed and also provides temper resistance through instantaneous clearing of all
memory when tempering is detected. This process is called rapid zeroization.The
NVRAM iButton memory can be erased or rewritten as often as necessary without wearing
out. High security is offered by the ability to erase the content of NVRAM extremely
quickly.
ROM
The java ring
contains 32kb of ROM .A special kind of operating system called Ecommerce. operating
system which is based on java and JVM is stored in the ROM.This operating system
handles all the operation which is happening in the iButton. It is stored in ROM
because it is not supposed to be altered by the user. The Crypto iButton hardware
platform offers a unique set of special features expressly designed to prevent private
keys and other confidential information from becoming available to hackers.
The java ring
provides very high degree of security for the confidential data that is stored
in the NVRAM memory. The barrier substrate and the triple layer technique effectively
deny access the unauthorized access to the
NVRAM confidential data. In
the worst case if
any unauthorized access penetrates the barrier the security processor detects
it and immediately the data which is written in the NVRAM. The Crypto iButton hardware
platform offers a unique set of special features expressly designed to prevent private
keys and other confidential information from becoming available to hackers.
