Abstract: “Electronic Toll Collection (ETC) is a charging method in intelligent transportation systems, which transmits information over ETC network. The information is subject to eavesdropping and interfering on ETC network owing to the defects of mutual authentication standard in Dedicated Short Range Communication (DSRC) protocol, the inherent security vulnerabilities of WSN and some other problems associated with the ETC network. In order to improve information security for ETC network and ensure every toll transaction could be successfully finished, we paid more attention to Wireless Sensor Network (WSN) as a part of the whole ETC network and proposed an information protection method based on a RC4-Logistic chaotic encryption algorithm. The proposed method not only enhanced the security of WSN in key manage and information encryption, but satisfied the limitation in battery and CPU power of wireless sensor nodes. The results from our experiments demonstrated that our propose method not only”
