这种情况有一个对应的算法,称为Pohlig-Hellman Algorithm: 对于一个群 G, g\in G ,若 g 的阶数 N 可被分解为若干素数的乘积 N=p_{1}^{e_{1}}p_{2}^{e_{2}}...p_{n}^{e_{n}} 的话。那么离散对数问题 g^{a}\equiv A\ (mod\ p) 可以用如下步骤解决: (1):对于 1\leq i \leq ...

Keywords:Primitive roots;Public key;Key Diffie-Hellman密钥交换算法(Diffie-Hellman Key Exchange Algorithm)是消息在传输过程中,为应对网络的不安全因素而进行的简单密钥交换,通信双方只能使用该算法计算出密钥对,而不能进行消息的加密和解密。而消息的加密与解密只能通过其他算法实现。 一、算法原理 Diffie-Hellman算法...
This paper introduces a security improvement that makes the Diffie-Hellman key agreement and encryption scheme more secure against attacks, such as the known plaintext attacks, it suggests the use of randomized parameter in both schemes, this will allows to produce a new shared secret key each ...

In this part, you are required to implement the Diffie–Hellman key exchange algorithm in Zp from scratch. (Hint: review the procedure of ElGamal algorithm). As the Setup procedure is the same as ElGamal algorithm, it is assumed that the public parameters of p and α are both set to cons...
