Suppose you want to prevent an attacker from finding a collision in a hash function. The attacker has enough computing power to calculate 240 hash values. You need to ensure that the attacker has only small chance of success but prefer the smallest acceptable output size. You have three possible output sizes to choose from. Which should you choose?
