在Brakerski等提出的基于LWE问题的属性加密体制基础上,提出了一个基于RLWE问题的属性加密体制。相比基于LWE问题的属性加密体制,该体制效率更高、密钥尺寸更小。在RLWE的安全性假设下,该体制支持长度不受限制的属性和半适应性安全。最后设计了一个编译器,利用该编译器可以将满足要求的属性加密体制转化为基于属性的全同态加密体制。
Based on the attribute-based encryption(ABE) scheme which was proposed by Brakerski and constructed on the LWE problem
a RLWE-based key-policy ABE scheme was presented.Efficiency and key size of this scheme over-takes old ones which are based on the LWE problem.Under the RLWE assumption
this scheme supports attributes of unbounded length and semi-adaptive security.Moreover
a compiler was constructed and could compile ABE scheme that meets its demand into an attribute-based fully homomorphic encryption (ABFHE) scheme.
