Abstract:

With the development of quantum computers, the latticebased cryptography becomes one of the cryptographic systems which can resist its attacks. This paper proposes an identitybased signature scheme with message recovery over lattice, which has the characteristics of high efficiency, counterfeit attack and short signature length and can be widely used in the field of lightweight authentication.

Key words: identity-based signature, lattice-based cryptography, message recovery
