支持电路结构的属性基加密研究综述

Review on attribute-based encryption for circuits

支持电路结构的属性基加密(attribute-based encryption,ABE)方案是在实现机密性和数据完整性的基础上,克服传统密码的访问控制单一等缺点,抵御“回溯攻击”提高信息安全性的一种新方法。指出电路结构的ABE机制并进行深入研究与讨论,分别分析和总结支持电路结构的基于密钥策略的加密属性(key-policy attribute-based encryption,KP-ABE)和基于密文策略加密属性(ciphertext-policy attribute-based encryption,CP-ABE)的设计和构造,提出现存的一些难题,并展望电路结构ABE的未来研究前景。

The attribute-based encryption(ABE)scheme supporting the circuit structure,which is based on the realization of confidentiality and data integrity,is a new approach to overcome the shortcomings of traditional passwords such as single access control and to resist"backtracking attacks"to improve information security.The ABE mechanism of the circuit structure is summarised and discussed,especially on the design and construction of the key-policy attribute-based encryption(KP-ABE)and (the ciphertext-policy attribute-based encryption,CP-ABE).The existing problems and the future research prospects of circuit structure ABE are also discussed.
