摘　　要：基于属性的签名（ABS：Attribute Based Signature）技术是近年来密码学界新兴的一种数字签名技术。签名者能选择满足验证策略的属性产生有效的签名，不泄露用户的身份或属性，实现匿名认证和细粒度访问控制，在访问控制领域具有广阔的应用前景。本文首先介绍与ABS相关的基本概念；然后深入探讨和综合分析了现有的研究工作，并对比各类ABS算法的功能及开销；最后讨论了ABS未来的主要研究方向。Attribute-based signatures（ABS） is a new digital signature technology in cryptography, in which a signer can choose its attributes satisfying a policy of a verifier to generate a valid signature without reveal its identity or attributes, resulting in anonymous authentication and fine-grained access control. Therefore, ABS has a broad prospect of application in the area of access control. After introducing the related concept, this study elaborates the existing research of ABS algorithms with an extensive comparison of their functionality and performance. Finally, this study discusses the main research directions of ABS in the future.
