EFFICIENT RC4 BASED ENCRYPTION SYSTEM FOR SENSOR NETWORK

摘要

In this paper we propose a new encryption technique for wireless sensor networks (3DSSec). Although RC4 is more susceptible to cryptanalysis attacks than RC5, the proposed encryption scheme has implemented RC4 in a way that boosts security when used in sensor networks and still allows a respectable performance/security trade off. The proposed encryption scheme is a good choice for Mica2 network sensors because it is based on an encryption algorithm that performs very well on Atmega128 platforms and has very modest memory demands. The encryption system seems a very good balance between performance and security given the limits of network sensors.
