OpenSSL 中的ECDH_compute_key()执行椭圆曲线 Diffie-Hellman 密钥协商,可在双方都是明文传输的情况下,协商出一个相同的密钥。 协商流程: 客户端随机生成一对公私钥 clientPublicKey,clientPrivateKey; 服务端随机生成一对公私钥 serverPublicKey,serverPrivateKey; ...

respectively. The attacks described in this paper are applicable to TLS-ECDH. The structure of this handshake is described in Fig.1. Our goal is to compute the private server keys. We may learn the public server keysPfrom the server certificate sent in theCertificatemessage, but since the Di...
