摘要
属性基加密作为一种新型的密码方案,将用户私钥和密文与属性相关联,为解决云存储环境下数据安全共享、细粒度访问控制和安全存储等问题提供了一种解决思路。在对密钥策略属性基加密、密文策略属性基加密和混合策略属性基加密深入研究后,根据不同的功能扩展,针对隐藏访问结构、多授权机构、复杂计算安全外包、可搜索加密机制、属性撤销、叛徒追踪等重点难点问题进行了深入探讨研究。最后总结了现有研究工作的不足,并指出了未来的研究方向。
As a new type of cryptography scheme,attribute-based encryption(ABE)associates the ciphertext and user’s secret key with attributes,and provides a solution for the security sharing,fine-grained access control and security storage of data in cloud storage environment.Based on the study of key-policy ABE,ciphertext-policy ABE and dual-policy ABE,according to the different function expansion,this paper elaborated the related works of ABE,including hidden access structure,multi-authorities,security outsourcing of complex computing,searchable encryption mechanism,attribute revocation,traitor tracing.Finally,this paper summarized the shortcomings of existing works and pointed out the future research directions.
