Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of NRF services access authorization. The method comprises generating, at a first device, an indication of whether an authorization is required for accessing a service provided by the first device; and transmitting the indication to a second device. With the solution of the present disclosure, the indication of whether an authorization is required for accessing a service provided by the NRF can be provided from the NRF to other NFs, which may improve the system performance without increasing the extra signaling overhead.

Abstract: Embodiments of the present disclosure relate to usage of access token in service based architecture. According to one aspect of the present disclosure, a first network device transmits an access token request to a second network device, and receives, from the second network device, an access token associated with a first count value, the first count value indicating the number of times the access token is allowed to be used. The first network device transmits, to a third network device, a service request with the access token; and receives, from the third network device, a service response determined based on the first count value and the access token. In this way, usage of an access token may be restricted and chance of misuse of the access token may be reduced.

Abstract: Example embodiments of the present disclosure relate to abnormal model behavior detection. A first apparatus obtains a machine learning model and expected behavior information of the machine learning model. The first apparatus monitors behavior information of the machine learning model during execution of the machine learning model; and determines occurrence of an abnormal behavior of the machine learning model during the execution by comparing the monitored behavior information with the expected behavior information.

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.
