Question: In a Local Key Establishment security context on a USIM, what happens if the Ks_local key derivation is not authorized by the local UICC policy (e.g., due to unauthorized Terminal_appli_ID/UICC_appli_ID association)?
Option 1: The USIM proceeds with key derivation using default parameters.
Option 2: The USIM abandons the function and returns the status word '6985' (Conditions of use not satisfied).
Option 3: The USIM requests additional authentication from the terminal before making a decision.
Option 4: The USIM automatically updates the local UICC policy to authorize the derivation.
Explanation: According to the specified behavior for Local Key Establishment security context on a USIM, if the Ks_local key derivation is not authorized by the local UICC policy (for reasons such as Terminal_appli_ID/UICC_appli_ID association not being authorized or an unauthorized Terminal_ID value), the USIM will abandon the function. In this scenario, the USIM returns a specific status word indicating that the conditions of use have not been satisfied, which is '6985'. This ensures security by preventing unauthorized key derivations.
