The Design and Implementation of DSRC Protocol-Based ETC Data-Communication Embedded System

In order to solve the data security, reliability problems of wireless communication in the ETC embedded data-communication system, this paper has analyzed the hardware structure which the system required, and paid an in-depth study on AES encryption algorithm that the hardware encryption engine applied. On this basis, the article has proposed the proposal that taking advantage of AES hardware encryption engine for full-text encryption of plain text in the wireless communication. Through experimental tests, it has proved the feasibility and the data wireless transmission security of ETC embedded data-communication system that the article designed.
