摘要:

针对无线传感器网络(WSN)中基于属性基加密(ABE)的属性授权与撤销问题,提出了一种结合信任管理的密文策略ABE方案(TM-CP-ABE)。该方案基于密文策略ABE,融合了信任管理机制,将信任评估和信任更新与属性授权和属性撤销结合起来。对方案的安全性、复杂性和有效性进行了对比分析,并与目前WSN中比较流行的加密方案进行了仿真实验对比,结果表明TM-CP-ABE方案较好地解决了无线传感器网络CP-ABE的属性撤销问题,并通过属性撤销在一定程度上抑制了恶意节点的破坏行为。

Abstract:

To solve the attributes authority and attributes revocation of Attribute-Based Encryption (ABE) in Wireless Sensor Network (WSN), a scheme of trust management-based ciphertext-policy ABE (TM-CP-ABE) was proposed. The proposed scheme was based on ciphertext-policy ABE and combined it with trust management mechanism. The procedure and the steps of trust evaluation based attributes authority and trust update based attributes revocation were provided. The security, complexity and validity of the proposed scheme were analyzed. Compared with the popular encryption scheme in WSN through comprehensive simulation, the results show that the proposed scheme is efficient for attribute revocation of CP-ABE in WSN. By attributes revocation, to a certain extent, the attacks of malicious nodes are also inhibited.
