Access token revocation in security management

Abstract

Example embodiments of the present disclosure relate to access token revocation in security management. In an example method, in response to providing, to a second device, an access token for the second device to access a NF service from a third device, a first device stores a mapping indicating an association among the access token, the second device and the third device. In response to determining that the second device is abnormal, the first device sends, to at least one target device based on the mapping, an indication of revoking the access token. In this way, at least one target device associated with revoked access token can be informed and potential damage caused by the abnormal NF can be eliminated.

Dependencies are inferred from the claim text.
