Anti-deception threshold signature scheme based on ECC

Threshold signature is a kind of signature system that comes from the combination of secret sharing and digital signature,and it properly solves the problems of key compromise and loss in key management,which is helpful to improve the system security.Based on the elliptic curve cryptography(ECC) and Shamir threshold mechanism,an anti-deception threshold signature scheme is proposed.No trusted party for generating and distributing keys shall be required for this scheme,and the secret communication is not needed when participants publish signature,which can effectively resist the interior and exterior attackers.The validity and security of the scheme was proved,and analysis shows that the security of the scheme is based on the intractability of the elliptic curve cryptography discrete logarithm problem and it requires no trusted party.
