摘要： The present disclosure provides a security mechanism to mitigate the risk of trackability of a D2D device engaged in groupcast communication. The security mechanism relies on the introduction of new parameters provisioned to the UE to facilitate the privacy protection of destination L2 identifiers used during group communication. The new parameters allow the UE to change the destination L2 Identifier so that an eavesdropper on the PC5 interface can no longer link several broadcast messages originating from the source UE and pertaining to a specific group.

摘要： A method is provided to operate a CN node to determine UP security activation. A UP session establishment request is obtained for a wireless device. An indication is obtained that the UP session establishment request is associated with an emergency session and/or that null ciphering and/or null integrity protection are applied to a CP associated with a CP session for the wireless device. It is determined that a UP should be configured for the UP session without activating integrity and/or confidentiality protection for the UP based on the indication. A UP security policy is provided to a RAN node associated with the wireless device, wherein the UP security policy indicates to configure the UP for the UP session without activating integrity and/or confidentiality protection based on determining that a UP should be configured for the UP session without activating integrity and/or confidentiality protection.

摘要： A network node (26, 400) is configured for use in a wireless communication network (10). The network node (26, 400) receives a request to establish a session (14-1) for a device (12-1) in a group (18), e.g., a 5G Local Area Network group (18). The network node (26, 400) determines a user plane security policy (24-1) for the session (!4-1), based on a user plane security policy (28) for the group (18). The user plane security policy (28) for the group (18) may specify a policy for securing a user plane path of a session for any device in the group (18). The network node (26, 400) may then transmit, to an access node of the wireless communication network (10), control signaling indicating the determined user plane security policy (24-1).

摘要： A method to operate an Access and Mobility Management Function (AMF) of a communications system that comprises an access node (AN) configured to communicate through a wireless air interface with user equipments (UEs) and that comprises a Session Management Function (SMF), is provided. The method includes receiving (910) an indication of a Max Data Radio Bearer Integrity Protection, DRB-IP, rate indicating a maximum computational capacity of the UE to process DRBs that have integrity protection during Packet Data Unit (PDU) sessions. A PDU session establishment request NAS message is received (920) from the UE for establishing a PDU session. A PDU session create message is communicated (930) toward the SMF. A SMF message is received (940) that contains an indication of an allocated DRB-IP rate for DRBs that are to be integrity protected for a PDU session being established.

摘要： A method to operate a UE for handling security policy for user plane protection of communications in a communications system is provided. The method includes transmitting a packet data unit (PDU) session establishment request network access stratum (NAS) message toward an Access and Mobility Management Function (AMF) to establish a PDU session. The 5 method further includes receiving an access network (AN) specific resource setup message indicating whether the UE is to activate integrity protection for data radio bearers (DRBs) serving the PDU session.
