Abstract

Wireless sensor networks are increasingly being integrated into the modern automobile with the intention of improving safety and reducing costs. However, it has been shown that the first widely-deployed and mandatory in-car sensor networks --Tire Pressure Monitoring Systems (TPMSs) -- employ no cryptographic algorithms for protecting their wireless communication, incurring serious security and privacy risks for consumers. In this paper, we design and evaluate cost-effective secure communication protocols that can resolve the privacy and security vulnerabilities of existing TPMSs as well as other forthcoming in-car wireless sensor networks. Our implementation on Arduino platforms shows that the proposed protocol incurs modest overhead and is applicable to resource-constrained embedded systems.
