Abstract: At present, the security of Elliptic Curve Cryptography is based on the elliptic curve discrete logarithm difficulty, and its safety index is full index. According to the safety, we design an Elliptic Curve Cryptosystem proxy multiple blind signature that combes with the proxy signature and the multi blindsignature features.This signature scheme has simple steps, highlevel security,and achieves the task of agency and the requirements of multisignature. And this signature scheme has blind signature characteristics, can verify the identity in the case of unknown authentication, and a rigorous proof proves this signature scheme is practical,safe and effective.

Key words: elliptic curve cryptography, multiple blind signature, proxy signature
