| Abstract: | By improving on the RC5 symmetric encryption algorithm, bring forward a RC5 cyclic covering chain algorithm. It is a joint algorithm of encryption, decryption and authenticity. It not only perfects many characteristics of RC5 algorithm, but also possesses performance of message authentication. It can apply to any kinds of files or data streams. By implementation of program, results indicate that the algorithm gets satisfying effect. |
