有什么问题,在这里都可以留言,有邮件通知的;
我也是个科研菜鸟,没啥多大的贡献。^ - ^

GPZMM20: TrustAccess: A Trustworthy Secure Ciphertext-Policy and Attribute Hiding Access Control Scheme Based on Blockchain
Lai11: Fully Secure Cipertext-Policy Hiding CP-ABE
属性撤销还没去了解过,不过应该不是很复杂的吧。

把人家的代码文档看看,主要是调用接口熟悉了,写代码也不是特别难,网上资源都有很多的。

您好,我想问一下能直接用cpabe进行加密明文吗,我看了一下基本上都是先用AES加密再属性加密这个密钥。

直接使用cpabe的话,如果能把明文映射到双线性配对空间的某个元素上,同时能把这个元素逆映射回去的话,那么就可以直接对明文的加密(两个过程分别对应明文参与加密,并能从密文解密)。但是,因为像cpabe这种非对称加密的计算效率没有对称加密高,一般作为密钥交换协议、签名协议等,对称加密则作为底层加密算法。
