The Elliptic Curve Sequential Multisignature Digital Scheme
Jingxin Hong · Journal of Xiamen University · 2005
In order to overcome the limitations of low efficiency and overtime in digital signatures,this paper advances a new scheme of sequence multisignature,which is based on the elliptic curve cryptosystem.This scheme uses time limits to avoid signature rebroadcasting,and the signature center can deal with the emergency according to the error messages in time,and it’s security is based on the difficulties of elliptic curve discrete logarithm problems.In addition,this scheme has the advantages of elliptic curve cryptosystem,such as shorter private key,less storage space,higher signature efficiency and so on.In the end,it analyzes the security of the scheme and proves the scheme’s validity.
