Question: What is the primary purpose of choosing a large value for the parameter "Choose" in the management of sequence numbers?
Option 1: To reduce the number of successful authentications required to force the counter in the USIM to wrap around.
Option 2: To increase the difficulty of an attack that aims to force the counter in the USIM to wrap around, thereby protecting against wrap-around attacks.
Option 3: To decrease the age limit for sequence numbers and make it more difficult to track user anonymity.
Option 4: To reduce the length of the array used for protection against wrap-around attacks.
Explanation: The correct answer is Option 2 because choosing a large value for the parameter "Choose" (in this case, 228) makes it more difficult for an attacker to force the counter in the USIM to wrap around. This is evident from the fact that an attack would require at least SEQmax/ = 215 > 32,000 successful authentications, making it a more secure option.
