改进后的 El Gamal加密解密法、数字签名算法 ,它是基于 x(x=gt(modp)代替生成元 g,并对传统的算法作些适当的变换而得到的 .公开 x,保密 g,使得攻击者在寻找私钥 t时无从下手 .由此 ,可以彻底消除了攻击者猜测私钥的空间 ,使得 El Gamal密码系统更安全 The improved El Gamal encryption and decryption method, which is based on x (x = gt (modp) instead of generating element g and making some appropriate transformations of the traditional algorithms, discloses x and secret g such that An attacker can not get started while searching for the private key t, thereby completely eliminating the space for the attacker to guess the private key and making the El Gamal password system more secure
