| description | Algorithm implemented on the mobile phone is different from one on PC． It requires little storage space and low power consumption． Standard AES S-box design uses look up table，and has high complexity and high power consumption，so it needs to be optimized when used in mobile phones． In our optimization AES encryption algorithm，the packet length is expanded to 256 bits，which would increase the security of our algorithm; look up table is replaced by adding the affine transformation based on inversion，which would reduce the storage space; operation is changed into 16-bit input and 64-bit output by merging the three steps，namely SubWords，ShiftＲows MixColumns and AddＲoundKey，which would improve the operation efficiency of the algorithm． The experimental results show that our algorithm not only can greatly enhance the encryption strength，but also maintain high computing efficiency． |
