Security Analysis of Wireless Sensor Networks in Intelligent Transportation Systems

摘要

The application of Wireless Sensor Networks (WSNs) in Intelligent Transportation Systems(ITSs)has been the topic of extensive research in the last decade．Transportation infrastructure is supported with the ingenious achievements of computer and information technology to resolve severe situations like traffic congestion and cope with emergency conditions like major accidents．Sensor nodes frequently report the data they capture to a central collection unit that analyzes the data and takes appropriate actions if needed．Due to inherent resource and computing constraints，security poses serious challenges in the application．In particular,the different aspects of security(confidentiality, integrity, and availability)strongly enticed the research devoted to ITSs．This paper presents an in-depth investigation of security problems unique to WSNs-based ITSs and analyzes some effective countermeasures to achieve a certain class of security．
