| 摘 要： | 在Rijndael加密算法中,每个明文块都要经过Nr+1圈的加密,而每一圈都要进行密钥加密处理。该文探讨了如何由给定的密钥种子(主密钥)生成各圈子密钥的方法,并给出了实现密钥扩展的主要C语言代码。

| Abstract: | Every message text block is encrypted for Nr+1rounds,and every round has key addition processing in the Rijndael encryption algorithm.This article discusses how to get the method of generating subkey in each round accord-ing to masterkey.The C program code of key expansion is also given. |
