摘要：In this paper we present a hybrid cryptographic technique implemented on System on chip, hybrid 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 HIGHT and RC4 cryptographic algorithm for block cipher and stream respectively in ALTERA Cyclone IV E, 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 (HIGHT) and lightweight cryptography (RC4) implemented on single SOC.
