Abstract:

Aiming at the problem that the existing IoT device secure access scheme is not applicable to resource-constrained IoT devices, a tPUF-based IoT device secure access scheme is proposed. Utilizing Physical Unclonable Function（PUF）, IoT devices do not need to store any secret information, enabling mutual authentication between the device and the authenticator, and negotiating session keys. It utilizes Trusted Network Connect（TNC） technology to achieve identity authentication, platform identity authentication, and integrity authentication of IoT devices from the authentication end. Security analysis shows that the scheme can effectively resist tampering, replication, and physical attacks. Experimental results show that, compared with other schemes, this scheme significantly reduces the equipment resource overhead.
