摘　　要：本文详细论述了网络分发中数据加密算法的基本概念、算法分类和各自的特点,重点分析了对称加密算法中的DES、AES和非对称加密算法中的RSA加密算法,在综合比较几种加密算法的基础上,结合实际应用,提出了一种新的加密算法-散列组合加密算法,新算法既满足了数据加密安全性的要求,也满足了加密效率的要求。The basic concept, classes and characteristic of data encryption algorithm in the process of data dissemination of map on Internet are discussed in this paper. The DES, AES algorithm in symmetry encryption algorithm and the RSA algorithm in non-symmetry encryption algorithm are discussed principally. Based on comparing these encryption algorithm, a new algorithm-hashing combination encryption algorithm is brought forward in this paper. The new encryption algorithm satisfies not only requirement of data encryption security, but also requirement of data encryption efficiency.
