pollard
- Pollard p-1算法实现 Pollard 方法由Pollard于1974年提出，其基本想法是这样的：设素数，由Fermat小定理，又有，因此就可能是的一个非平凡因子。当然，问题在于我们并不知道是多少。一个合理的假设是的因子都很小，比如说，所有素因子都包含在因子基中，我们来尝试着找到一个能够“覆盖”，即是说，从而，因此我们可以转而求来获得所要的非平凡因子。例如设素因子上限为，便可以简单的取或是最小公倍数.-Pollard p-1 algorithm

456
- RSA算法的C语言实现 1.密钥的产生 (1)选两个安全的大素数p和q。 (2)计算n=p×q，φ(n)=(p-1)(q-1)，其中φ(n)是n的欧拉函数值。 (3)选一整数e，满足1<e<φ(n)，且gcd(φ(n),e)=1。 (4)计算d，满足de≡1 modφ(n)，即d是e在模φ(n)下的乘法逆元，因e与φ(n)互素，由模运算可知，它的乘法逆元一定存在。 (5)以{e,n}为公开钥，{d,n}为秘密钥。 2.加密 加密时首先将明文M比特串分组
Elgamal
- 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 rando
MerkleHellman
- The encryption algorithm using Merkle-Hellman knapsacks starts with a binary message. * The message is envisioned as a binary sequence P = [p1, p2, … ,pk]. * Divide the message into blocks of m bits, Po = [P1, P2, ... ,Pm], P1 = [Pm+1, .
discrete_log
- Solve descrete log problem using meet in the middle attack. More formally, write a program to compute discrete log modulo a prime p. Let g be some element in Z p and suppose you are given h in Z p such that h = gx where 1 ≤ x ≤ 240. Your goal
diffie_hellman
- Implement Diffie-Hellman Key exchange protocol and demonstrate that at the end, both person will have a common Key. Do the following: 1. Set a variable p ( e.g. p = 37) and g (e.g. g = 5). 2. Generate a, a random number mod p. Now generate A,
