Abstract
Examples pertaining to indication of additional security capabilities using non-access stratum (NAS) signaling in 5th Generation (5G) mobile communications are described. A processor of an apparatus (e.g., a user equipment (UE)) transmits an initial NAS message to a communication entity of a 5G mobile network. The processor then receives a message from the communication entity responsive to the transmitting, the message comprising an additional 5G security parameter information element (IE). The processor proceeds to perform a security mode control procedure using information contained in the additional 5G security parameter IE pertaining to at least one 5G security parameter.
Claims11
A method, comprising:
- transmitting, by a processor of an apparatus, an initial non-access stratum (NAS) message to a communication entity of a 5th Generation (5G) mobile network;
- receiving, by the processor, a message from the communication entity responsive to the transmitting, the message comprising additional 5G security information;
- and
- using, by the processor, the additional 5G security information in a security mode control procedure,
- wherein the additional 5G security information is comprised in an information element (IE) including a horizontal derivation parameter (HDP),
- wherein at least one of a plurality of bits of the IE indicates whether derivation of a key for an Access and Mobility management Function (KAMF) is required, and
- wherein the at least one of the plurality of bits of the IE is a least significant bit (LSB) in an octet.
An apparatus, comprising:
- a transceiver which, during operation, wirelessly communicates with a communication entity of a 5th Generation (5G) mobile network;
- and
- a processor coupled to the transceiver such that, during operation, the processor performs operations comprising:
- transmitting, via the transceiver, an initial non-access stratum (NAS) message to the communication entity of the 5G mobile network;
- receiving, via the transceiver, a message from the communication entity responsive to the transmitting, the message comprising additional 5G security information;
- and
- using the additional 5G security information in a security mode control procedure,
- wherein the additional 5G security information is comprised in an information element (IE) including a horizontal derivation parameter (HDP),
- wherein at least one of a plurality of bits of the IE indicates whether derivation of a key for an Access and Mobility management Function (KAMF) is required, and
- wherein the at least one of the plurality of bits of the IE is a least significant bit (LSB) in an octet.
