With the development of cryptography, the attribute-based encryption (ABE) draws widespread attention of the researchers in recent years. The ABE scheme, which belongs to the public key encryption mechanism, takes attributes as public key and associates them with the ciphertext or the user's secret key. It is an efficient way to solve open problems in access control scenarios, for example, how to provide data confidentiality and expressive access control at the same time. In this paper, we survey the basic ABE scheme and its two variants: the key-policy ABE (KP-ABE) scheme and the ciphertext-policy ABE (CP-ABE) scheme. We also pay attention to other researches relating to the ABE schemes, including multiauthority, user/attribute revocation, accountability, and proxy reencryption, with an extensive comparison of their functionality and performance. Finally, possible future works and some conclusions are pointed out.
随着密码学的发展，基于属性的加密（ABE）近年来受到了研究人员的广泛关注。ABE 方案属于公钥加密机制，它将属性作为公钥，并将其与密文或用户的私钥相关联。它是解决访问控制场景中开放性问题的一种有效方法，例如，如何同时提供数据保密性和具有表现力的访问控制。在本文中，我们综述了基本的 ABE 方案及其两种变体：密钥策略 ABE（KP-ABE）方案和密文策略 ABE（CP-ABE）方案。我们还关注与 ABE 方案相关的其他研究，包括多授权机构、用户/属性撤销、可问责性和代理重加密，并对它们的功能和性能进行了广泛比较。最后，指出了可能的未来工作和一些结论。
