摘　　要：介绍了分组密码Rijndael算法,比较了两种高效实现Rijndael算法中列混淆变换方法,并对基于32位ARM9微处理器提出了有效的改进方法。对这两种方法实现的空间与时间效率进行了实验比较,测试结果表明列混淆变换结果正确且高效。Rijndael algorithm of block cipher is introduced briefly. Two efficient implementation of mixcolumn operations are compared respectively and an improved implementation is proposed based on 32-bit embedded microprocessor ARM9. Their efficiency is compared in space and time with experiments. The experimental results show that improved implementation works well and efficiently.
