Proposed RC4 algorithm generates two bytes per clock cycle. Encryption is performed by using two keys and two blocks of plain texts. Similarly, decryption is performed by using the two keys and two blocks of cipher texts.SAIPRIYA SAMALAP.NAVITHADR. M.GURUNADHA BABU

RC4 Algorithm In the RC4 encryption algorithm, the key stream is completely independent of the plaintext used. An 8 * 8 S-Box (S0 S255), where each of the entries is a permutation of the numbers 0 to 255, and the permutation is a function of the variable length key. There are two...

A rising input on the START port triggers the beginning of a cryptographic operation, using the either the KEY or Sin inputs to initialize the keystream. In any case the old state is evacuated via the Sout pins. The core then starts to output the keystream per RC4 algorithm. ...

介绍 在密码学中,RC4(Rivest Cipher 4,也称为ARC4或ARCFOUR,意为所谓的RC4)是一种流密码。尽管它以简单性和软件速度着称,但在RC4中发现了多个漏洞,使其不安全。当不丢弃输出密钥流的开头或使用非随机或相关密钥时,它特别容易受到攻击。RC4的使用特别有问题,导致协
