WebOct 3, 2024 · Starter Diffie-Hellman Starter 1 (10 pts.) The Diffie-Hellman algorithm works with finite fields and modular exponentiation to allow to parties to exchange a shared secret. If you’re not familiar with this algorithm or with the math behind it I would suggest to check out the Wikipedia page to get started. WebJan 19, 2015 · No You can't, to compute the secret key you must first be able to compute a (Alice's secret key) or b( Bob's secret key) this will require the evesdropper to compute the discrete logarithm and since there isn't any known efficient algotrithm that can compute that than Deffie_Hellmen is pretty secure, and the third party (the evesdropper) will never know …

WebJun 30, 2016 · Diffie-Hellman算法具有两个吸引力的特征: 1、仅当需要时才生成密钥,减小了将密钥存储很长一段时间而致使遭受攻击的机会。 2、除对全局参数的约定外,密钥交换不需要事先存在的基础结构。 然而,该技术也存在许多不足: 1、没有提供双方身份的任何信息。 2、它是计算密集性的,因此容易遭受阻塞性攻击,即对手请求大量的密钥。 受攻击者 … WebNote that Diffie-Hellman works in a multiplicative group: a group where the multiplication is used as the defined binary operation.
