Description: ElGamal算法既能用于数据加密也能用于数字签名，其安全性依赖于计算有限域上离散对数这一难题。
密钥对产生办法。首先选择一个素数p，两个随机数, g 和x，g, x < p, 计算 y = g^x ( mod p )，则其公钥为 y, g 和p。私钥是x。g和p可由一组用户共享。
ElGamal用于数字签名。被签信息为M，首先选择一个-ElGamal algorithm not only used for data encryption can be used for digital signatures, their safety depends on the calculation of a finite field discrete logarithm this problem. Key to the method. First of all, choose a prime number p, the two random numbers, g and x, g, x <p, computing y = g ^ x (mod p), for its public key y, g and p.

Description: 求离散对数的shanks算法，要求如下：
实现计算 Zp 中计算离散对数的 Shanks 算法，基本要求如下：
1）p 是一个小素数( 小于 32 bit )，a 是一个本原元。程序的输入为(p, a, b), 输出为 logab ( mod p) (可以用 log3525 (mod 809)等作为测试)；
2）采用快速模指数算法求幂（如am），采用扩展欧几里得算法求逆（ 如a-i (mod p) ）；
3）采用一种好的排序算法对 L1、L2 排序；
4）采用概率算法（如Miller Rabin算法）自动生成素数 p，采用本原元的充要条件自动生成 a；-Discrete number of shanks on demand algorithm, the following: calculation of Zp calculated to achieve the discrete logarithm Shanks algorithm, the basic requirements are as follows: 1) p is a small prime number (less than 32 bit), a is a primitive element. Process input (p, a, b), output logab (mod p) (can use log3525 (mod 809) so as a test) 2) The fast mode index algorithm to solve the power (such as the am), using extended Euclidean Reed inverse algorithm (such as ai (mod p)) 3) use a good sorting algorithm on the L1, L2 sort 4) using probabilistic algorithms (such as the Miller Rabin algorithm) automatically primes p, using primitive element automatically generate the necessary and sufficient conditions a
