Abstract: In the present invention, we introduce a novel mechanism called evidence indistinguishable key consensus, and construct an efficient, modular, flexible, and strongly secure signature scheme on this basis. In the design of the traditional lattice-based signature scheme, a public key thereof is an MLWE instance t＝(t1, t0)＝As+e. In order to reduce the size of the public key, it is possible to use only t1 as a signature public key, and use t0 as a part of a private key, wherein t0 corresponds to a lower bit of t, and t1 corresponds to an upper bit of t. In the present invention, during signature, we simultaneously use the real t  0  and several t'  0  converted from t  0  and used for confounding. This mechanism can greatly improve the signature efficiency and improve the security of the private key.
