it was classified until 1997 * The RSA scheme is a block cipher in which the plain text and cipher text are integers between 0 and n-1 for some n. * A Typical size of n is 1024 bits or 309 decimal digits. * This is a public key encryption scheme. * In this scheme two pairs of integers {e‚ n} and {d‚ n} are used. First of them i.e. {e.n} is called the RSA public key and the other one i.e. {d‚ n} is called the RSA secret key. * The sender uses the public key and encrypts

1 INTRODUCTION 1. Introduction The idea of a single smart card to be used for multiple services has been around for years. Instead of using separate access devices for different services‚ a user can access multiple services from different service providers by a single smart card. For example‚ a user can use the same smart card to log on to a remote server system‚ enter a secure building‚ and perform a financial transaction. This kind of design frees people from carrying many cards‚

ATMs ensure security. The machines used as ATMs usually work on the specially designed cryptoprocessors‚ which help in the encryption and decryption of the personal information of users. The encryption of the information entered by the people leads to higher levels of security and leads to fraud prevention. There are special authentication codes that are used for the encryption and decryption of the messages and information entered by the users. This is the biggest safety measure. Another important
