Question: In LTE WLAN Aggregation, what is the purpose of the input parameters FC, P0, and L0 when deriving S-KWT from KeNB between the eNB and UE?
Option 1: To authenticate the UE's identity in the WLAN network
Option 2: To establish an encrypted tunnel for data transmission
Option 3: To synchronize the eNB and UE clocks for timing alignment
Option 4: To generate a unique key (S-KWT) for securing LTE-WLAN aggregation
Explanation: The correct answer is Option 4 because, in the context of LTE WLAN Aggregation, deriving S-KWT (a unique key) from KeNB (the eNB’s key) using specific input parameters (FC, P0, and L0) is crucial for securing the aggregated link between LTE and WLAN. This process ensures confidentiality and integrity of data transmitted over both networks.
