| 摘 要： | 首先利用RSA加密算法对数据进行加密和解密，实现了数据的安全传输；然后针对RSA加密算法时间开销大和算法设计复杂的缺点，提出基于乘同余对称特性的SMM算法。通过对该改进RSA加密算法的实现发现加密运算速度明显提高且算法更简单，从而证明了本文所提改进算法的有效性。

| Abstract: | In this paper, encryption and decryption is achieved firstly by using the RSA encryption algorithm and the data is trans- mitted safely. Then, aiming at the shortcoming of large time consumption and complexity of the RSA eneryption algorithm, a new fast RSA algorithm is presented, which is an improvement of a fast RSA algorithm based on symmetry of modulo mtdtiplieation （ SMM algo- rithm）. The caleulated speed is improved obviously and the algorithm is simpler than the previous algorithm, whieh can prove the ef- fectiveness of the improved algorithm that proposed in this paper. |
