【Abstract】 Based on RSA and threshold scheme,a cheat-proof signature scheme was proposed.This system separates the key into several shares by threshold scheme,distributes them to certain participants and introduces the concept of sub-verifying-key.Therefore,the issues of the leakage and loss the key are effectivety solved.Facts show that its a secure and feasible signature scheme.更多还原
