| Abstract: | SM-AES （S-Box Modified AES） algorithm refers to a new AES encryption algorithm which uses a replacement scheme of S- box. This paper uses SM-AES encryption algorithm to encrypt the database processing. It improves resistance to cryptanalytic attacks by replacing the original S-box in AES algorithm. The performance of the improved S-box has enhanced greatly compared to the previous AES S-boxes. And if this kind of improved S-box is used in database encryption system, it will improve its non-linear and differential physical characteristics of the algorithm and improve the security of dalabase. |
