摘　　要：随着量子计算机的发展,格密码成为可抵抗其攻击的密码体制之一。在格密码基础上提出了一种具有消息恢复功能的身份签名方案,具有高效、抵抗伪造攻击、签名长度短的特点,可广泛应用于轻量级认证领域。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.

关 键 词：身份签名 格密码 消息恢复
