name: AV
full_form: Authentication Vector
context: The IMSI is encrypted using the AV_Key using the method agreed at step 1. 3. The UE sends an Attach Request message that includes the encrypted IMSI (encrypted with the AV_Key) and AV_Key(encrypted with the public key of the HSS) to the MME. It also include the MCC and MNC of its HPLMN. 4. MME requests an AV from the HPLMN HSS (using the MCC and MNC received for the UE to rout the message to the correct HSS). It includes the encrypted IMSI and AV_Key received in the Attach Request. 5. HPLMN HSS decrypts the received encrypted AV_Key and then uses this to decrypt the received encrypted IMSI. 6. HPLMN HSS generates a new AV for the IMSI 7. HPLMN HSS protects AV using the provided AV_Key. The encryption is done in such a way that the AV still has the form RAND, AUTN, XRES and KASME so it can be treated as a regular AV by the MME. 8. HPLMN HSS selects an Attach-IMSI to assign to this attachment and sends both this Attach-IMSI and protected AV to the MME. The Attach-IMSI has identical
description: The Authentication Vector (AV) is a crucial element in mobile network authentication. It comprises RAND, AUTN, XRES, and KASME components, all secured using an AV_Key for robust authentication of user equipment (UE).
explanation: The text describes the AV as a parameter specifically used in the authentication process of user equipment within a mobile network, making it an Authentication Parameter.
