Chaos Theory and DNA Computation Based Data Encryption System for E-Healthcare Monitoring System

Abstract

The body area sensor network consists of small motes, such devices are considerably energy constrained, limited computation capabilities, and small size of memory such that most advanced encryption scheme cannot be implemented in this type of sensor network. An encryption algorithm must be designed to be a tradeoff between simple computation and powerful encryption scheme. Our proposed algorithm consists of combination of two approaches DNA computation and chaos theory to improve the one-time pad encryption technique. In this work a small amount of memory capacity is required since acquiring samples were encrypted individually in real time. The proposed algorithm appears to be very secure. In this paper, we will explain briefly the design of the proposed algorithm and show its efficiency through encryption tests. Also the effect of some sample loss due to collision occurs in the communication has been studied. The algorithm has been simulated using MATLAB and tested practically using shimmer sensor network platform.
