第18题：
There are two general approaches to attacking a ( )encryption scheme.The first attack is known as cryptanalysis.Cryptanalytic attacks rely on the nature of the algorithm plus perhaps some knowledge of the general characteristics of the ( ) or even some sample plaintext- ciphertext pairs. This type of ( ) exploits the characteristics of the algorithm to attempt to deduce a specific plaintext or to deduce the key being used.

The second method, known as the ( 4 )-force attack, is to try every possible key on a piece of ( ) until an intelligible translation into plaintext is obtained. On average, half of all possible keys must be tried to achieve success.
