摘　　要：设计了一套基于IDEA&RSA相结合的数据加密系统方案,即用IDEA来加密需传输的保密数据信息,同时使用RSA来传送密钥,并对具体的算法进行了改进.实现的IDEA&RSA组合加密方式,具有速度快、不需要进行密钥秘密分配且保密管理的密钥量较少等特点.Compared IDEA with RSA, a new combined cipher technology scheme based on IDEA＆RSA was designed. By analyzing and verifying, that combined cipher has better security than one of them has indicated. RSA algorithm has been improved since it is running rather slowly.
