Question: In the key establishment between a Universal Integrated Circuit Card (UICC) and a terminal, what is the maximum allowed length for the Terminal_ID (P1) input parameter in octets?
Option 1: 8 octets
Option 2: 16 octets
Option 3: 32 octets
Option 4: 10 octets
Explanation: According to the specified input parameters for key derivation in UICC-terminal interactions, the Terminal_ID (denoted as P1) has a variable length that does not exceed 10 octets. This constraint is crucial for ensuring standardized and secure key establishment processes within the defined telecom framework.
