Abstract
Wireless sensor network (WSN) consists of many hosts called sensors. These sensors can sense a phenomenon (motion, temperature, humidity, average, max, min, etc.) and represent what they sense in a form of data. There are many applications for WSNs including object tracking and monitoring where in most of the cases these objects need protection. In these applications, data privacy itself might not be as important as the privacy of source location. In addition to the source location privacy, sink location privacy should also be provided. Providing an efficient end-to-end privacy solution would be a challenging task to achieve due to the open nature of the WSN. The key schemes needed for end-to-end location privacy are anonymity, observability, capture likelihood, and safety period. We extend this work to allow for countermeasures against multi-local and global adversaries. We present a network model protected against a sophisticated threat model: passive /active and local/multi-local/global attacks. This work provides a solution for end-to-end anonymity and location privacy as well. We will introduce a framework called fortified anonymous communication (FAC) protocol for WSN.
Highlights
Wireless sensor networks (WSNs) consist of many hosts called sensor nodes (SNs)
In order to protect the panda from hunters or adversaries (ADVs), we need to implement in place an efficient source location privacy scheme (SLP)
We conclude of these simulations that the performance of energy controlled anti temporal (ECAT) is better than simple global anti temporal (SGAT) while it continues to provide a good temporal privacy
Summary
A wireless sensor device is a simple autonomous host device. It can sense a phenomenon, convert the sensed information into a form of data, process the data and transmit the data to a sink or a base-station (BS) for further usage or analysis. In order to protect the panda from hunters or adversaries (ADVs), we need to implement in place an efficient source location privacy scheme (SLP). In such a scenario, location privacy is much more important than the confidentiality of the sensed data itself. Base-station location privacy (BLP) is very crucial for every WSN since it aggregates all the data
