19. 21. 22. 8. 8. GBA_U message flow (continued) 1. An application in the UE has come to a state that it needs application-specific GAA keys from the GBA module in the UE. Thus, it contacts the GBA module in the UE and gives it the NAF_ID. The NAF_ID consists of the FQDN of the NAF application server and a Ua security protocol identifier. 2. The GBA module contacts the USIM application in the UICC and asks for the International Mobile Subscriber Identity (IMSI) of the USIM. IMSI is the unique identifier of the USIM application that is used in HSS to find the counterpart key of the subscriber in the subscriber database.

For example, if a protocol supports username/password-based authentication scheme, GAA can be plugged in and used there almost directly. , (U)SIM cards) in different deployment scenarios and, in particular, make life easier for the users by not requiring to remember a large range of username/password combinations. Instead of remembering passwords, users are able to reuse their cellular authentication in a secure and automated manner. Therefore, the Ua reference point has not been selected to use one single protocol.

The BSF initializes the generation and storage of the bootstrapping session data to its internal session database. The actual storage and data management in the BSF is vendor implementation specific, but at least the AV, GUSS and key generation timestamp should be stored for further requests and processing. 11. 6. 0c41” 12. 103] applies). 13. Upon successful validation of RAND and AUTN, the USIM returns RES, CK and IK to the GBA module. The GBA module establishes the GAA master session key (Ks) by concatenating CK and IK received from the card.
