中文摘要: 提出了支持多布尔函数的公开可验证委托模型, 并基于支持非单调访问结构的KP-ABE(Key Policy Attribute Based Encryption)方案给出了具体的构造. 该方案能够使任何第三方对布尔函数的委托计算结果进行验证. 与Parno等人的方案相比较, 该方案通过将输入值与委托计算的布尔函数进行绑定, 实现了一次系统建立后, 可对多个布尔函数进行委托计算, 提高了系统的效率.
Abstract:This paper proposes a publicly verifiable delegation model for multi-boolean-function, and gives a construction based on key-policy attribute based encryption (KP-ABE) supporting non-monotonic access structure. In our scheme, any third party could verify the result of the delegation for the boolean-function. Compared to the construction proposed by Parno, our scheme is more efficient, since it can delegate multi-boolean-function after the setup of the system, by binding the inputs to the specific boolean-function .
