ABSTRACT
The aim of this paper is to describe the implementation of a lowpower,low-cost 16-bit RISC microcontroller that will act as thecore of a stand-alone security system. The controller is designedto provide moderate-high security at very low cost and to be ableto operate independent of a database. It is designed using 1.5-mSCMOS process from MOSIS and operates at a frequency of 12.5MHz.

ABSTRACT
The origin of smart cards began when consumer requirements for convenience and security outpaced the capabilities of magnetic stripe cards. Providing increased data storage and added security, smart cards were introduced in Europe in the early 1980â„¢s as stored value cards for payphones. These early smart cards were disposable, and were an effective means to reduce losses. Todayâ„¢s smart cards are re-usable, hold large quantities of data, speed transaction times, identify the cardholder, and even provide loyalty benefits. A ....etc

Abstract-


Comparator-controlled power switch has been widely used to improve power efficiencies of discontinuous-conductionmode (DCM) buck regulators. Some major design challenges are capabilities of the comparator to operate at low voltage and dissipat ....etc

A smart card, simply speaking, is a credit card sized plastic card with an embedded computer chip and some memory. You can put it to a wide variety of uses to help simplify your daily life. Shopping, identification, telephone services and licenses are just couples of them. ISO 7816 defines the smart cards standard it details the physical, electrical, mechanical and application programming interface for it.

Smart card technology Smart card technology has its historical origin in the late 60's and 70's when inventors in Germany, Japan and Fran ....etc

LOW-POWER LOW -AREA MULTIPLIER BASED ON SHIFT AND ADD ARCHITECHTURE
Multipliers
Multipliers are among the fundamental components of many digital systems
The largest contribution to the total power consumption in the multiplier is due to the generation of partial product
Among all the multipliers shift and add multipliers are the most commonly used ,due to its simplicity & relatively small area requirement

ABSTRACT
The on-card implementation is actually a prime finding problem.So we should optimize the algorithms so that they become efficient, flexible and space saving. Along with these crypto coprocessors are also used to accelerate cryptography.Although smart cards are becoming used in an increasing number of applications, there is small literature of the implementation issues for smart cards. This paper describes the issues and considerations that need to be taken into account when implementing the key ge ....etc

AN AREA-EFFICIENT UNIVERSAL CRYPTOGRAPHY PROCESSOR FOR SMART CARDS
Cryptography circuits for smart cards and portable electronic devices provide user authentication and secure data communication. These circuits should, in general, occupy small chip area, consume low power, handle several cryptography algorithms, and provide acceptable performance. This project is based on a hardware implementation of three standard cryptography algorithms on a universal architecture.The microcode cryptography processor targets smar ....etc
