摘要 将椭圆曲线密码机制与ElGamal机制、ECDSA机制进行了对比,提出了一种新的签名机制。这种机制可以抵挡自主选择消息攻击,并且不用求逆,效率高。 Elliptic Curve Cryptosystem,ElGamal system and ECDSA system are compared,a new signing scheme is proposed and analyzed.The scheme is provably secure against adaptively chosen-message attack,and is quite pratical without inverse.
