Problems solved by technology
[0006] The embodiment of the present application provides an authentication method, device and system to at least solve the problem of how to deal with the remaining unused n-1 AVs and the possible waste of performance and memory resources
Based on this scheme, it can not only solve the problem of how to deal with the remaining unused n-1 first authentication vectors in the prior art and the possible waste of performance and memory resources, thereby improving the performance of the first authentication vector Efficiency in use; and it can reduce the problem of terminal authentication failure caused by the link between the security anchor functional entity and the authentication entity, thereby improving the reliability of the authentication result

The embodiments of the present application provide an authentication method, device, and system to at least solve the problem of how to deal with the remaining unused n-1 AVs that may result in waste of performance and memory resources. The method includes: the authentication entity receives n first authentication vectors from the unified data management entity, where n is a positive integer; the authentication entity generates n second authentication vectors according to the n first authentication vectors; the The authentication entity sends one of the n second authentication vectors to the security anchor functional entity; the authentication entity receives the authentication confirmation request from the security anchor functional entity, and according to the authentication Authorization confirmation request to perform authentication confirmation on the terminal; in the case of successful authentication confirmation, the authentication entity sends other unused n-1 second authentication vectors among the n second authentication vectors to the security anchor functional entity Authentication vector.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to an authentication method, device and system. Background technique [0002] In the authentication process of the user registration process described in the 3rd generation partnership project (3GPP) technical standard (TS) 33.501 v0.40, if the unified data management (unified data) in the home network The authentication algorithm selected by the management (UDM) entity is the 5th generation-authentication and key agreement (5G-AKA), so the UDM entity may generate n authentication vectors (authentication vector, AV) at a time , n is a positive integer. Further, an authentication server function (authentication server function, AUSF) entity in the home network may receive n AVs from the UDM entity. However, for some security anchor function (security anchor function, SEAF) entities in the visited network with a lower trust category, the AUSF entity may only send...
