ECDH: 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。交换双方可以在不共享任何秘密的情况下协商出一个密钥。ECC是建立在基于椭圆曲线的离散对数问题上的密码体制,给定椭圆曲线上的一个点P,一个整数k,求解Q=kP很容易;给定一个点P、Q,知道Q=kP,求整数k确是一个难题。ECDH即建立在此数学难题之上。
ECDH密钥协商支持ECC算法,SM2做为一种ECC椭圆曲线,没有在HarmonyOS加解密算法库框架中提供ECDH算法。HarmonyOS put_get 2024-11-08 10:46:53 浏览 赞 收藏0 回答1 分享 回答1 按赞同 / 按时间 FengTianYa 可以通过引入三方库:https://github.com/Tongsuo-Project/Tongsuo的so并调用c接口...
