A PUF-based IoT Authentication Model in Edge Computing Environment

Edge computing proposes to solve the problems such as high bandwidth load and long delays when a great number of terminal devices connect to the IoT. However, the addition of the edge layer also poses new challenges to authentication security between devices at all levels of the IoT. The characteristics and communication requirements of cloud, edge, and terminal devices in the edge computing environment has been analyzed, and four types of authentication schemes is designed, which provides a basis for further research on the authentication problem of IoT devices in edge computing environment.
