Redundancy Removal of Shifted Keys Using Pseudo Random Bit Generators in Wireless Sensor Network

摘要

In a wireless sensor network, confidentiality is provided by using encryption algorithms on the sensor values. This can be enhanced by avoiding the reuse of the same key for different sensors. In the process of manipulating the key for use on the next sensor, there is a shift operation that could lead to no variation in the key value. An invariable key produces the same encrypted value for the same sensor value. This paper aims to provide a solution against this stagnant key value using the concept of Pseudorandom Bit Generator.
