Question: In a 5G network, where is the SUCI (Subscriber Concealed Identifier) calculation primarily performed, according to 3GPP specifications for USIM application management?
Option 1: At the Network Server, as part of the authentication process
Option 2: By the Mobile Equipment (ME), utilizing specific EFs like EFSUCI_Calc_Info
Option 3: Jointly by the ME and the Network in a collaborative security protocol
Option 4: Exclusively within the USIM application itself, without ME involvement
Explanation: The SUCI calculation is performed by the Mobile Equipment (ME), which reads specific information from the EFSUCI_Calc_Info file on the USIM, highlighting the ME's central role in this security-related calculation to protect subscriber identity.
