RSA is the most widely used digital signature algorithm in e-commerce and the complexity of large integer operation is the main factor that affects the efficiency of a RSA system. In this paper, a n carry array based large integer denotation approach is proposed to speed up the large integer calculation in RSA key generation and data encryption/decryption(More)
This paper proposes a Rossler chaos system based image encryption scheme, which improves the security and performance over the conventional simple chaos system based ones. The balance and correlation properties of the time sequences generated by Rossler system are analyzed and a pre-process scheme is proposed, which makes the key stream have good(More)
