Trusted Wireless Sensor Node Platform

Abstract

A bstract— Security problems related to Wireless Sensor Networks (WSN) has directly influenced the credibility of WSN applications and its services. With the advancement and demand in the WSN applications such as in military, structural health monitoring, transportation, agriculture, smart home and many more, the system stands to be exposed to too many potential threats. Currently, WSN systems has mainly relied on software based security for protection against breach of systems and data integrity. As WSN systems become more ubiquitous, software based security is regarded as no more sufficient for WSN applications. This paper discusses security issues in WSN area and reviews work done on hardware base security. Based on the preliminary works that have been carried out, Trusted Platform Module (TPM) initiatives by Trusted Computing Groups (TCG) together with Trusted Zone technologies by ARM are seen as possible approaches toward better security implementation in WSN. Finally, this paper proposes new embedded security implementation utilizing 32-bit ARM11 processor with trustzone features to enhance the integrity of the sensor node platform.
