为了防御无线传感器网络中的时空推断攻击,基于MIX思想提出一种新的时空相关性隐私数据保护机制,针对数据传输过程中存在的3种时空关联关系对应的隐私数据提出相应的保护策略,详细阐述保护机制的实现原理和数据处理流程,为WSN时空相关性隐私数据的保护提供一种新的思路。
To prevent the timing attacks of spatio-temporal in wireless sensor networks,a new privacy preservation mechanism based on MIX idea is proposed. The protection strategies corresponding to three different spatio-temporal relations existed in data transmission are proposed. The realization principle and data processing flow of the protection mechanism are described in detail,thus it provides a new idea for the protection of spatio-temporal privacy in WSN.
