Hiding contextual information in WSNs
2012
2012 IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM)
We address the problem of preserving the confidentiality of contextual information in wireless sensor networks (WSNs). Such information includes the time and location of events observed by the WSN, the position of the sink, and possible routes to the sink. Contextual information can be extracted via traffic analysis, even when all traffic is encrypted. We consider a global threat model in which the adversary is assumed to be capable of eavesdropping on all communications. Compared to previous
