Title: Threshold Proxy Signature Scheme Based on Elliptic Curve Cryptography
Abstract: In 2000,Hsu et al.presented a new nonrepudiable proxy signature scheme with known signers based Sun' scheme and discrete logarithm cryptography.The scheme meets several fundamental requirements and can effectively withstand the conspiracy attack and the forgery attack.However,discrete logarithm cryptography has some drawbacks like longer keys and difficult key management,which seriously limit application of the scheme proposed by Hsu et al.In allusion to this,this paper proposes a threshold proxy scheme based on elliptic curve cryptography with an advantage of short keys.
