Method for synchronization of home network key
The present disclosure provides a terminal including a memory; and a processor, comprising hardware, configured to perform a primary authentication between the terminal and a network in 5G for a third party service, derive a security key, K AUSF , and derive an identifier for the security key from the security key.
1. A terminal comprising:
a memory; and
a processor, comprising hardware, configured to:
perform a procedure of a primary authentication between the terminal and a network in 5G for an Authentication and Key Management for Applications (AKMA);
generate a security key, Key of Authentication Server Function (AUSF) (KAUSF), during the procedure; and
consider the primary authentication as successful and store the security key, KAUSF, upon receiving a Non Access Stratum (NAS) security mode command (SMC) message from the network in 5G.
2. The terminal according to claim 1 , wherein the primary authentication comprises 5G AKA or EAP-AKA′.
3. The terminal according to claim 1 , wherein the processor is further configured to:
generate an identifier from the security key; and
transmit a message including the identifier.
4. The terminal according to claim 1 , wherein the network in 5G comprises AUSF.
5. The terminal according to claim 4 , wherein the security key is used for the AKMA.
6. A method comprising:
performing a procedure of a primary authentication between a terminal and a network in 5G for an Authentication and Key Management for Applications (AKMA);
generating a security key, Key of Authentication Server Function (AUSF) (KAUSF), during the procedure; and
considering the primary authentication as successful and storing the security key, KAUSF, upon receiving a Non Access Stratum (NAS) security mode command (SMC) message from the network in 5G.
7. The method according to claim 6 , wherein the primary authentication comprises 5G AKA or EAP-AKA′.
8. The method according to claim 6 further comprising:
generating an identifier from the security key; and
transmitting a message including the identifier.
9. The method according to claim 6 , wherein the network in 5G comprises AUSF.
10. The method according to claim 9 , wherein the security key is used for the AKMA.
11. A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:
performing a procedure of a primary authentication between a terminal and a network in 5G for an Authentication and Key Management for Applications (AKMA);
generating a security key, Key of Authentication Server Function (AUSF) (KAUSF), during the procedure; and
considering the primary authentication as successful and storing the security key, KAUSF, upon receiving a Non Access Stratum (NAS) security mode command (SMC) from the network in 5G.
12. The non-transitory computer readable medium according to claim 11 , wherein the network in 5G comprises AUSF.
13. The non-transitory computer readable medium according to claim 11 , wherein the primary authentication comprises 5G AKA or EAP-AKA′.
14. The non-transitory computer readable medium according to claim 11 , wherein the process further comprises:
generating an identifier from the security key; and
transmitting a message including the identifier.
15. The non-transitory computer readable medium according to claim 12 , wherein the security key is used for the AKMA.
