这个软件是一个Java实现基于“ciphertext-policy属性加密”(CP-ABE)。　　　使用该软件,您需要Java加密为基础的配对库(jPBC)安装(jpbc-1.2.0测试)。

用于CP_ABE相关方案的编程。The cpabe toolkit provides a set of programs implementing a ciphertext-policy attribute-based encryption scheme. It uses the PBC library for the algebraic operations. Note that the cpabe toolkit might not compile against versions of PBC older than 0.5.4.
