SOC Based Cryptosystem Implementation Using RC4 and IDEA Algorithm

In this paper we present a RC4 & IDEA cryptographic technique implemented on System on chip, IDEA in the sense that we are going to implement both stream cipher and block cipher in a SOC. The encryption of data will be performed by different cipher base on the application. . Here we are integrating IDEA and RC4 cryptographic algorithm for block cipher and stream respectively, so that we can achieve both encryption of data for transmitting through the communication link (i. e. stream cipher) and encryption data like files and images (i. e. Block cipher) can be implemented in single SOC. Finally we are computing the efficiency for both ultra lightweight cryptography (IDEA) and lightweight cryptography (RC4) implemented on single SOC.
