  • Publication number: 20230020994
    Abstract: Apparatuses, methods, and systems are disclosed for security mode integrity verification. One method includes receiving an authentication request message corresponding to a user equipment. The method includes, in response to receiving the authentication request message, determining whether the user equipment has moved from a first public land mobile network to a second public land mobile network within a predetermined period of time. The method includes, in response to the user equipment having moved from the first public land mobile network to the second public land mobile network within the predetermined period of time, determining a likelihood factor that indicates a likelihood that the user equipment moved from the first public land mobile network to the second public land mobile network. The method includes, in response to the likelihood factor being less than a predetermined threshold, transmitting an authentication response message indicating a failed authentication.

  • Patent number: 11546757
    Abstract: Apparatuses, methods, and systems are disclosed for protecting the user identity and credentials. One apparatus includes a processor registers with a mobile communication network using a first set of credentials, the mobile communication network supporting a plurality of network slices. The processor receives a public key for a network slice where slice-specific authentication is required and encrypts a second set of credentials using the public key. Here, the second set of credentials is used for authentication with the network slice. The apparatus includes a transceiver that sends a message to the mobile communication network, the message including the encrypted second set of credentials.

  • Patent number: 11539699
    Abstract: Apparatuses, methods, and systems are disclosed for network slice authentication. One apparatus includes a processor that provides an application layer and a non-access stratum (“NAS”) layer and a transceiver for communicating with a mobile communication network. The processor receives, at an application at the application layer, network slice authentication information for a subscribed service and stores the network slice authentication information at an application module. The processor associates the network slice authentication information with single network slice selection assistance information (“S-NSSAI”) and registers the application with the NAS layer, said registration pointing to the associated S-NSSAI. Additionally, the transceiver that exchanges, via the NAS layer, authentication messages with an authentication, authorization, and accounting (“AAA”) server for network slice authentication information.
