| Abstract: | 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. |
