An improved method of elliptic curve cryptosystem digital signature
Xiaoping Zhang · Information technology newsletter · 2006
This paper represents an improved method of digital signature,which is based on the principle of combined public key(CPK) and combined with the algorithm of elliptic curve cryptosystem(ECC).In this method a pair of private keys are introduced to sign the message,and via the combination of CPK and ECC,effective management of keys and high reliability have been achieved.Compared with the traditional methods of digital signature,it is more secure and convenient.At last,the security of this method has been analyzed.
