User+int private_key+int public_key+void generate_keys()+int compute_shared_key(int other_public_key) 在这个类图中,User类代表一个参与密钥交换的用户。每个用户都有私钥和公钥,并提供生成密钥和计算共享密钥的方法。 结尾 至此,我们完成了Diffie-Hellman算法的Python实现。我们首先确定了算法的核心步骤,然后...

以下是使用Python实现Diffie-Hellman密钥交换算法的示例: ```python import random from sympy import mod_inverse # 定义两个大质数 p = 23 q = 113 # 计算n和phi n = p * q phi = (p - 1) * (q - 1) # Alice选择一个私钥a a = random.randint(1, phi) # Bob选择一个私钥b b = random...
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...
上面的图就是Diffie-Hellman密钥交换算法,假如x要向y发送消息,如果采用上面的算法,那么需要如下几个步骤: 1.生成两个共享的质数 G 和P,并将这两个数在x和y中共享。 P是一个非常大的质数,而G是P的生成元(生成元的乘方结果和1~P-1中的数字是一一对应的)。
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 ...

In particular, in the OpenSSH package, we distribute the/etc/ssh/modulifile that includes tens of prime numbers of different sizes. Those primes will be used for diffie-hellman-group-exchange-sha1, diffie-hellman-group-exchange-sha256, or gss-gex-sha1-* key exchanges. With the security of...
