中文摘要:
      无线体域网作为一种新型网络,被广泛应用到健康医疗、紧急救护等领域。然而,无线体域网收集到的数据大部分都是与用户个人有关的信息,在实际的应用部署过程中必然会面临严重的敏感隐私数据泄露或者被恶意篡改的风险。为了保证体域网环境下用户数据的隐私安全性,提出了一种数据安全混合传输机制,即基于多环模式的K匿名混合传输算法(AMT-ML),其主要思想是对通信节点进行网络划分,将其分成若干个通信环网络,并将K匿名方案应用到层次模型的感知层与传输层,通过进行多次K匿名处理来保证每一层的用户数据在概率上是相对安全的。实验结果显示,AMT-ML算法的隐私保护性优于基于单环模式的K匿名混合传输算法(AMT-SL),二层网络中多环模式的通信距离也小于单环模式的通信距离。
英文摘要:
      Wireless body area network,as a new type of network,is widely used in health care,emergency rescue and other fields.However,the data collected by wireless body area network are mostly related to user’s personal information.In the actual application of the deployment process,it is bound to face serious sensitive privacy data leakage or malicious tampering risks.In order to protect the privacy security of user data in the body area network environment,this paper proposed a data security mix transmission mechanism,which is a K-anonymous mix transmission algorithm based on single-loop model (AMT-ML).The main idea is to divide the communication nodes into several communication loop networks,and apply the K anonymous scheme to the perceptual layer and the transport layer of hierarchical model.In order to ensure that the user data in each layer are relatively safe,this paper used multiple K anonymous processing.The experimental results show that the privacy protection of AMT-ML is superior to K-anonymous mix transmission algorithm based on single-loop model (AMT-SL) algorithm,and the communication distance of the multi-loop mode in the two layer network is less than that of the single-loop mode.
