Research and realization based on hybrid encryption algorithm of improved AES and ECC

Advanced Encryption Standard (AES) and Elliptic Curve Cryptosystems (ECC) is the best two algorithms of symmetric encryption technology and asymmetric encryption technology. The paper analyzes the AES algorithm and S-box structure, then the replace plan based on S-box structure is proposed to improve AES encryption algorithm, secondly the ECC algorithm is been discussed. Based on this we put forward an mix encryption scheme of improved AES and ECC. This plan has high operation speed, high security performance and strong usability.
