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。
提齣瞭支持多佈爾函數的公開可驗證委託模型，併基于支持非單調訪問結構的 KP-ABE(Key Policy Attribute Based Encryption)方案給齣瞭具體的構造。該方案能夠使任何第三方對佈爾函數的委託計算結果進行驗證。與Parno等人的方案相比較，該方案通過將輸入值與委託計算的佈爾函數進行綁定，實現瞭一次繫統建立後，可對多箇佈爾函數進行委託計算，提高瞭繫統的效率。

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 .
