The meet-in-the-middle attack uses a space-time tradeoff to find the cryptographic key in only encryptions -LRB- and space -RRB- versus the expected encryptions -LRB- but only space -RRB- of the naive attack .

The meet-in-the-middle attack attack uses a space-time tradeoff to find the cryptographic key in only encryptions -LRB- and space -RRB- compared to the expected encryptions -LRB- but only space -RRB- of the normal attack .
