Abstract: Negotiating security mechanisms (300) between user equipment and a network. In an embodiment, an access and mobility management function (212) is operatively coupled to user equipment (106). The access and mobility management function comprises a means (1504) for identifying security capabilities of the user equipment in supporting one or more non-access stratum combined integrity and encryption algorithms (1050), a means (1504) for selecting a non-access stratum combined integrity and encryption algorithm from the one or more non-access stratum combined integrity and encryption algorithms to protect non-access stratum signaling, and a means (1502) for sending a non-access stratum security mode command message (2312) to the user equipment indicating the non-access stratum combined integrity and encryption algorithm.

Abstract: Security mechanisms (300) between user equipment and a network. In an embodiment, a network (101) is operatively coupled to user equipment (106). A network element (212/1600), when operating as a sender (810) of a sent message (1720) to the user equipment, comprises a means (1504/1606) for identifying a combined integrity and encryption algorithm (1000), a means (1504/1606) for deriving a combined integrity and encryption key (1010) for the combined integrity and encryption algorithm, and a means (1504/1606) for applying the combined integrity and encryption algorithm to the sent message using the combined integrity and encryption key as an input parameter (1002), to provide security protection to the sent message.

Abstract: Techniques are disclosed for verifying user equipment compliance. For example, a method comprises computing, via user equipment, a secure identifier for the user equipment comprising an equipment identifier of the user equipment, and sending the secure identifier comprising the equipment identifier in a request message from the user equipment to a communication network to which the user equipment is attempting to connect. The communication network performs compliance verification for the user equipment based at least in part on the equipment identifier securely received from the user equipment.

Abstract: There is provided an apparatus comprising means for determining a change of connection at a user equipment from a source access point to a target access point, and means for receiving, from the target access point, an indication that an associated gateway function is the same for the source access point and the target access point. The apparatus also comprising means for generating an access point key based on the received indication from the target access point, and means for securing communications with the target access point using the generated access point key.
