A Sequential Digital Multi-signature Scheme Based on Elliptic Curves
Ronghua Shi, Hu Fang · Computer Engineering and Applications Journal · 2006
This paper advances a new scheme of sequence multi-signature,which is based on the elliptic curve cryptosystem,and its security is based on the difficulties of elliptic curve discrete logarithm problems.In this scheme,message is sent to the signatory secretly;The signatory can validate the last signature to discover fake signature,at the same time the signature center can deal with the emergency according to the error message in time,it also can validate the validity of signatory's public key so as to avoid the cheating by inner users.The scheme takes full advantage of elliptic curve cryptosystem,such as shorter private key,higher signature efficiency and so on,so it can reduce the cost of communication and improve the security of network.
