LIGHTWEIGHT AUTHENTICATION METHOD SUPPORTING ANONYMOUS ACCESS OF HETEROGENEOUS TERMINAL IN EDGE COMPUTING SCENARIO

摘要

Provided by the present invention is a lightweight authentication method supporting anonymous access of heterogeneous terminal in an edge computing scenario. The present invention uses a cloud platform to create a pseudo identity for each terminal device to hide the true identity information, and can meanwhile trace a malicious terminal device. During the authentication process of terminal devices accessing an edge computing node, the edge computing node can verify the legality of the identities of all accessing devices without communicating with the cloud platform, and will not learn the true identity information of the terminals. The present invention guarantees the identity privacy of terminal devices, improves the efficiency of access authentication, and can resist common threats such as replay attacks, thereby enhancing the security and reliability of the entire edge computing system, and solving the problem of access authentication of terminal devices with limited resources in an edge computing scenario.
