摘要

Rijndael算法的高效实现一直是研究的热点。本文首先分析了Rijndael的加密过程，在此基础上提出了基于校验表的快速加密方法。主要方法是构造s-table和mixcolumn-list。通过对表或列表进行2次校验和12次简单的圆移位和取模2求和，就可以实现对明文的加密。从而提高了Rijndael算法的实现效率。同时分析了Rijndael算法相对于DES算法的优异性能。

Efficient Realization of Rijndael and Its Performance Analysis

The efficient realization of Rijndael algorithm is always a hotpot in research. This paper at first analyzes encryption process of Rijndael, and then it puts forward speedy encryption means based on check-table. The chief method is constructing s-table and mixcolumn-list. By checking table or list twice and 12 times simple circle shift and sum modulo 2, the encrypting of the plaintext can be realized. Thereby the realization efficiency of Rijndael algorithm is improved. At the same time this paper analyzes the excellent performances of Rijndael algorithm in contrast to DES.
