摘要
RNS(余数数制系统)是一种整数运算系统,在粒度精确性、能源损耗和响应速度方面有着很大的优势。CCMP协议是无线网络中对数据进行加密解密以及完整性校验的协议。该文中提出了新的基于RNS和CCMP系列协议结合的分组迭代算法,该算法能更有效地抵抗高阶差分密码分析。同时在FPGA上的实现上该算法也显示了明显的速度优势。该文中的架构被映射到Altera 10K系列的FPGA上。
RNS (Residue Number System) is a kind of integer operation system,and it allows interesting advantages in terms of precision, power, consumption and speed. CCMP is an agreement about encryption and authentication on WLAN. This paperpresents a general algorithm based on RNS. The algorithm can process high-level cipher analysis,and show the fastest in the following comparions.
