非对称加密算法Diffie-Hellman算法

Diffie-Hellman算法是一种非对称加密算法，主要用于在公开通信网络上创建共享密钥。该算法允许两个用户通过非安全通道交换信息，然后生成一个共享的秘密密钥，该密钥可以用于加密和解密后续通信。 Diffie-Hellman算法的核心在于离散对数的数学困难性。具体来说，它依赖于以下三个主要步骤： ...

RSA公钥密码算法和Diffie-Hellman密钥交换

公钥加密算法的诞生对称加密算法的弊端需要保存额外的密钥，密钥的管理难公钥的使用需要找到一种算法，正向推解容易，反向求解困难：模运算：求余运算--单向函数模运算原理推解求余算法不可逆，只可以通过正向求解算法得出指数x，对模运算求逆不现实当mod的数足够的大，指数x基...

听说这玩意可以安全交换密钥 —— Diffie-Hellman 算法

Diffie-Hellman 密钥的配送一直是一个难以解决的问题，我们始终无法保证在不安全的线路中安全传递密钥。直到 Diffie-Hellman 密钥交换算法出现：一种确保共享密钥安全穿越不安全网络的方法。 Diffie-Hellman 密钥交换算法，是由 Whitfield Diff...

JAVA上加密算法的实现用例MD5/SHA1，DSA，DESede/DES，Diffie-Hellman的使用(转)

源文作者王辉第1章基础知识 1.1. 单钥密码体制单钥密码体制是一种传统的加密算法，是指信息的发送方和接收方共同使用同一把密钥进行加解密。通常,使用的加密算法比较简便高效,密钥简短，加解密速度快，破译极其困难。但是加密的安全性依靠密钥保管的安全性,在公开的计算机网络上安全地传送和保管密钥是一个...
