| 摘 要： | 基于Serpent密钥生成算法, 提出一种改进的Rijndael密钥生成算法. 在改进过程中, 采用由连续两轮密钥生成下一轮密钥的方法, 使得Rijndael密钥生成算法在密钥生成过程中同样具有不可推导的特点, 从而提高了原有算法在密钥生成方面的安全性.

| Abstract: | For improving the security of Rijndael algorithm in the process of key generation, a character callednon-deduction was summarized. With this character, the Rijndael key schedule was improved. We made useof continuous two round keys to generate the next round keys, which made the Rijndael key schedule alsopossess the character non-deduction. Therefore the security of the original key generation algorithm wasenhanced. |
