A Security Reinforcement Technology of Telematics Box Based on Secure Element

Abstract

The telematics box is a vehicle communication terminal in the Internet of Vehicles, used to collect data from electronic control units and transfer data between users and application server. With the rapid development of Internet of Vehicles, T-Box provides users personalized service and abundant entertainment. However, it also becomes easy to cause security problems, such as disclosure of private information of owners, illegal control of vehicles and so on. Therefore, it is very important to reinforce the security of T-Box. To reinforce the security of T-Box, this paper will present a security reinforcement technology, which uses a secure element and traditional security measures to implements secure boot based on TrustZone and security service. This paper designs a software hierarchical model of security service based on the research of AUTOSAR and make innovative improvements to Transport Layer Security. Besides, to validate the feasibility of the solution, this paper also implements a security reinforcement technology and verifies the validity of it.
