TR 21.905,
TS 33.220 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in
TR 21.905.
AUTN(*):
In GBA context, GBA_ME relies on AUTN value to verify that the authentication vector is from an authorised network, while GBA_U relies on AUTN* to perform network authentication as described in [1]. AUTN(*) is used to refer both to AUTN and AUTN*.
AUTS:
Disposable-Ks model:
The keying model used in GBA-push. Only one NAF-key is generated per Ks and the Ks cannot be reused.
GBA_U aware UICC:
A UICC which supports GBA_U which means that the Ks will never leave the UICC.
GBA-Push-Info:
GBA-Push-Info contains data relevant for key derivation in GBA Push. GBA-Push_Info is sent via the Upa-reference point from the NAF to the UE.
NAF_Id:
The FQDN of the NAF, concatenated with the Ua security protocol identifier,
NAF-key:
A NAF-key derived from Ks. It can be used to refer to Ks_(int/ext)_NAF or Ks_NAF.
NAF SA:
A security association between a NAF and a UE based on a NAF-key.
Push-message:
This is a message that is sent on a Ua-reference point from the NAF to the UE and has applied GBA keys that were bootstrapped via the Upa-reference point.
Push-NAF:
A NAF authorized for using GBA-Push.
UE_Trp:
The transport address used for delivery of GPI to the UE.
For the purposes of the present document, the abbreviations given in
TR 21.905 and the following apply. An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in
TR 21.905.
