摘要
公共移动网络中用户隐私信息的泄露成为无线传感网络的安全隐患,因此隐私保护是网络信息安全研究的重点课题之一。提出运用改进蚁群算法保护公共移动网络中节点位置信息。利用蚁群最优理论给出内在路由探索方法,通过信息素局部更新控制信息素的挥发情况,使数据包在不同节点间实现数据传输,根据蚁群理论中数据随机传输的特性,使攻击方无法获取已捕获数据包的来源节点,从而达到网络源节点位置隐私保护的目的;对于汇聚节点位置隐私问题,提出了动态路由协议理论,根据SA-DRP路由协议,以不同概率向安全区域及非安全区域发送数据包,且须保证以上两个区域接收真实包等同于虚假包,并使汇聚节点转发虚假包的方式保护该节点位置隐私。实验证明,利用文中方法可以有效保护公共移动网络节点位置。
The leakage of users' privacy information in public mobile network becomes a security risk of wireless sensor network, so privacy protection is one of the key issues in network information security research, and the improved ant colony algorithm is proposed to protect node location information in public mobile network. The ant colony optimization theory is used for the internal routing exploring approach. The pheromone volatilization is controlled by pheromone local update, so that the packet data transmission between different nodes is realized and the attacker cannot get the source nodes of its captured data packet according to the characteristics of data transmission in random ant colony theory, so as to achieve the purpose of privacy protection of the network source node location; as for the sink node location privacy problem, a dynamic routing protocol theory is proposed, with which data packets are sent to the safety and non-safety areas in different probability according to the SA-DRP routing protocol. In this process, the above two areas must be ensured to receive the real package equivalent to false packets, and the false packets must be transmitted by the sink nodes to protect these nodes' location privacy. The experiment results show that the proposed method can effectively protect the node location of public mobile network.
