| 摘 要： | 基于3维对偶正交基的技术，提出了一种新的密钥策略的基于属性的加密方案。该方案在素数阶群上构造，支持单调访问结构，具有自适应安全性。方案利用双重系统加密的证明方法将方案的自适应安全性归约到判定线性假设。与同样是自适应安全的密钥策略ABE方案相比，提出的方案在同等安全性上具有更高的效率。

| Abstract: | A new key-policy attribute-based encryption scheme based on 3 dimension dual orthonormal bases was proposed.This scheme was constructed in prime order groups with adaptive security and supporting access structures.It has been proved the security from decisional linear assumption by using dual system encryption technique.Compared with previous key-policy ABE scheme which is also adaptively secure,the scheme is more efficient at the same security level. |
