摘　　要：在IDEA算法的基础上,分析其存在的弱密钥,其加密过程也决定了相同的明文必定加密成相同的密文,容易暴露明文的统计学特性。设计了基于IDEA算法的加密算法X_IDEA,较好地解决了IDEA算法的弱密钥问题。X_IDEA算法的加密过程中嵌套IDEA算法,特殊的加密过程设计使得其安全性和抗攻击能力较IDEA算法更强。Based on the IDEA algorithm, introduced plaintext encrypted surely into a common ciphertext. It is X_IDEA algorithm based of IDEA algorithm, which gives a process nested the IDEA algorithm, and special encryption algorithm stronger. the existence of weak keys, its encryption process determine the same very easy to expose the statistical characteristic of expressly. Design the good solution to the problem of weak key IDEA algorithm. It＇s encryption process design makes its safety and against the attack ability more IDEA
