摘要
针对开放通信信道的信息安全问题,采用发送方身份认证(数字签名)的方式,设计了一种类似RSA算法的基于离散对数问题的快速信息安全传输加密算法.通过数值举例演绎了该算法的系统设计(选择私钥和公钥)、加密、信息传输、解密和信息恢复等步骤.理论分析和仿真结果表明,该算法的执行速度比RSA算法快2倍,而所需的指数运算比ElGamal加密算法减少50%.因此,该算法是一个安全的、快速的、确定性的方案.
Aiming at the safety problem on open communication channel, a fast information security transmission method is proposed based on discrete logarithm problem by sender identification ( digital signature) , which is simi-lar to RSA algorithm. The whole steps of the algorithm are deduced by numerical examples, including the system design ( selection of private keys and public keys) , encryption, information transmission, decryption, and informa-tion recovery. The comparative analysis and the simulation results prove that it is twice times faster than the RSA algorithm, and needs 50% fewer exponential operations than the ElGamal encryption algorithm. So the proposed al-gorithm is a safe, quick and deterministic method.
