WebApr 14, 2024 · 1.W.Diffie与M.Hellman在1976年提出一个称为Diffie-Hellman密钥交换的公钥密码算法。 该算法能用来在两个用户之间安全地交换密钥材料,从而使双方得到一个共享的会话密钥,但该算法只能用于交换密钥,不能用于加/解密。 WebJul 14, 2024 · RSA and the Diffie-Hellman Key Exchange are the two most popular encryption algorithms that solve the same problem in different ways. In a nutshell, the Diffie Hellman approach generates a public and private key on both sides of the transaction, but only shares the public key. Unlike Diffie-Hellman, the RSA algorithm can be used for …
