Title: Secure Threshold Proxy Signature Scheme Based on Elliptic Curve Cryptography
Abstract: Most threshold proxy signature schemes are constructed on the base of discrete logarithm in infinite fields.Discrete logarithm cryptography based on ElGamal has some drawbacks such as long keys and difficult key management,which seriously limit its practical application.Elliptic curve cryptography is introduced and a threshold proxy signature scheme based on the cryptography is proposed,which can satisfy the properties of the threshold proxy signature,and withstand the conspiracy attack.
