Focusing on the problem of high counter memory overhead and frequent overflow of counter mode encryption
this paper proposes an efficient scheme of protecting data confidentiality and integrity.Based on the locality character of data accessing
the scheme set different counter lengths for memory area of different accessing frequency and the counter lengths can be dynamic adjusted.Analysis and simulation results indicate the scheme can decrease memory overhead and the number of overflow.
