System on Chip for Sensor Network Security: A Proposed Architecture

The loss of confidential data results adversary effect while transmission in sensor network. The whole sensor network is then prone to get exposed to the intruder. Hence we need a strong mechanism, rather a hardware oriented solution to protect such sensitive data. In this paper we propose an alternative approach of securing data through an introduction of a hardware component called the linear feedback shift register (LFSR). The kind of network that we have considered is a hierarchical clustering sensor network. This technique mask all the intermediate, input and output data with some values in order to de-corelate information leaked, if any, so that the original/actual information is not exposed to the intruder. We propose an architecture embedded on a chip of the sensor node which is to be modified to incorporate a new component capable of generating random numbers to mask the output.
