name: MGV-S
full_form: MBMS key Generation and Validation Storage
context: It is assumed that the UE includes a secure storage (MGV-S). This MGV-S may be realized on the ME or on the UICC. The MGV-F is implemented in a protected execution environment to prevent leakage of security sensitive information such as MBMS keys. MGV-S stores the MBMS keys and MGV-F performs the functions that should not be exposed to unprotected parts of the ME. An overview of ME based key management and UICC based key management in UE is described in figures 4.2a and 4.2b. In particular in ME based key management it shall be ensured that the keys are not exposed to unprotected parts of the ME when they are transmitted from the UICC to the MGV-S or during the key derivations.

description: The MGV-S (MBMS key Generation and Validation Storage) is a secure storage component within the User Equipment (UE) that stores sensitive information such as MBMS keys. It plays a crucial role in ensuring the security of key management processes, including key transmission and derivation.
explanation: MGV-S is classified as a Network Function because it is a specific functional entity within the UE's security architecture responsible for storing and managing sensitive security information, as described in the context from 3GPP TS 33.246.
