针对基于密钥策略属性基加密(KP-ABE, key-policy attribute-based encryption)方案不能兼顾属性撤销和用户身份追踪的问题, |
The existing key-policy attribute-based encryption (KP-ABE) scheme can not balance the problem of attribute revocation and user identity tracking. |

提出一种支持可撤销和可追踪的 KP-ABE 方案。 |
Hence, a KP-ABE scheme which supported revocable and traceable was proposed. |

首先,该方案能够在不更新系统公钥和用户私钥的情况下实现对用户属性的撤销,更新代价比较小, |
The scheme could revoke the user attributes without updating the system public key and user private key with a less update cost. |

同时可以根据解密密钥追踪到用户身份,从而有效地防止匿名用户的密钥泄露问题。 |
Meanwhile, it could trace the user identity based on decryption key which could effectively prevent anonymous user key leakage problem. |

其次,该方案基于线性访问结构(LSSS, linear secret sharing scheme),与树形访问结构相比,执行效率更高。 |
The proposed scheme was based on linear secret sharing scheme (LSSS), which was more efficient than tree-based access structure. |

最后,该方案基于判定性 q-BDHE 假设,给出了在标准模式下的安全性证明。 |
Based on the deterministic q-BDHE hypothesis, the proposed scheme gave security proof until standard mode. |

通过与已有的 KP-ABE 方案进行对比分析得出,该方案的公钥长度更短、加解密的计算开销更低,且在实现属性可撤销的基础上实现了用户身份的可追踪功能,具有较为明显的优势。 |
Finally, compared with the existing KP-ABE scheme, the scheme has a shorter public key length, lower computational overhead and realizes the traceability function of user identity based on the revocable attribute, which has obvious advantages. |

针对物联网服务功能链部署问题,将网络功能虚拟化(NFV, network function virtualization)与软件定义网络(SDN, software defined networking)相结合, |
Aiming at the problem of IoT service function chain deployment, network function virtualization (NFV) and software defined networking (SDN) were combined to optimize resources. |
