中文摘要:
      提出了一个具有较小解密代价的密文策略属性基加密(CP ABE)方案,并在标准模型下证明了其安全性。进而提出一个适用于移动对等传感器网络(MP2PWSN)的基于CP ABE的组密钥管理协议。在该协议下,移动节点和簇头节点首先完成簇间组密钥分发,然后由簇头进行簇内组密钥分发。该协议满足后向安全性,支持节点动态加入,退出以及节点撤销,还能实现细粒度的传感器数据访问控制和隐私保护。仿真结果表明,该协议由于采用低解密代价的CP ABE算法,传感器节点的能耗不随属性数量的增多而显著增加,因此能够较好地满足MP2PWSN的匿名组通信安全需求
英文摘要:
      A new ciphertext policy attribute based encryption(CP ABE) scheme with lower decryption cost was presented, and it was proved secure in a stand model. Then a group key management protocol based on CP ABE was proposed for mobile peer to peer wireless sensor networks (MP2PWSN). Under this protocol, mobile nodes and cluster heads firstly complete the inter cluster group key distribution, and then a cluster head distributes the group key within its cluster. This protocol satisfies the backward security, permits node dynamically joining, leaving and being revoked, and also implements the control of fine grained sensor data access and privacy preserving. The simulation results show that sensors’ energy consumption does not greatly increase with the number of attributes because the protocol uses a CP ABE algorithm with lower decryption cost.Therefore, this protocol can meet the security requirements of anonymous group communication for MP2PWSN
