alicePubKey * bobPrivKey = bobPubKey * alicePrivKey = secret The ECDH algorithm (Elliptic Curve Diffie–Hellman Key Exchange) is trivial: Alice generates a random ECC key pair: {alicePrivKey, alicePubKey = alicePrivKey * G} Bob generates a random ECC key pair: {bobPrivKey, bobPubKey =...

ECDH全称是椭圆曲线迪菲-赫尔曼秘钥交换(Elliptic Curve Diffie–Hellman key Exchange),主要是用来在一个不安全的通道中建立起安全的共有加密资料,一般来说交换的都是私钥,这个密钥一般作为“对称加密”的密钥而被双方在后续数据传输中使用。ECDH是ECC算法和DH结合使用,用于密钥磋商,这个密钥交换算法称为ECDH。交换双方...
