Abstract:

With the widespread applications of the IoT, the security protection of terminal device is weak and the security events occurr frequently. Only effective measures are taken from the bottom of the system, the security of IoT can be improved. As the latest achievement of the trusted computing, DICE technology applies a new solution for security problems of IoT terminal. It can provide not only device identity protection, data encryption and identity authentication, but also the updating mechanism coping with the complex IoT environment. Based on the DICE technology, it takes the RFID reader as the research object in this paper. By analyzing the startup process of this device, an approach of the establishment and extension of the chain of trust is designed and the scheme of DICE-based mesurement and updating for IoT terminal is proposed, which can ensure the security of read-write operation and data uploading of the RFID reader. In the C compiler environment, the scheme of chain of trust transfer and measurement based on DICE are implemented.
