Research on Applications of Chaos Cryptography to M-Commerce Security

Based on the study of algorithm of existing chaotic encryption, a new algorithm of "one-packet-one-cipher" was presented. In the proposed cipher, a new AES algorithm based on chaos map was created. The keys generated from chaotic sequence are used as sub-key for AES block ciphers. The possibility of mixing both the advantages of block ciphers and one-time pad ciphers in one encryption scheme was analyzed in this paper. Such cipher schemes which have both the features of block ciphers and stream ciphers have good properties on anti-attacks. And thus, the schemes will have a good future on M-Commerce Security.
