摘要

针对计数器模式加密存在的counter存储开销大，容易溢出的问题，本文提出一种高效的数据机密性和完整性保护方法，它基于数据访问的局部特性，为内存访问频率不同的区域设置不同的counter长度，且counter长度可动态调整.分析和模拟实验表明，该方法可降低内存开销并减少溢出次数.

Abstract

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.
