在2005欧洲加密大会上,Sahai和Waters[7]引入了基于属性的加密(ABE)的概念。ABE实现了基于公钥的一对多加密,被认为是实现可扩展和细粒度访问控制系统的一种很有前途的密码原语。ABE方案有两种[1],密钥策略ABE(KP-ABE)和密文策略ABE(CP-ABE)。在本文中,我们关注的是后者。
At Eurocrypt 2005, Sahai and Waters [7] introduced the concept of attribute-based encryption (ABE). ABE enables public key based one-to-many encryption and is envisioned as a promising cryptographic primitive for realizing scalable and fine-grained access control systems. There are two kinds of ABE schemes [1], key-policy ABE (KP-ABE) and ciphertext-policy ABE (CP-ABE) schemes. This paper, our concern is on the latter.
