A coupling diagram shows:

a. How the data is passed from one module to another. b. The test values of the variables. c. How the modules process the data. d. Where the variables are located in the modules.

Answer the following statements true (T) or false (F)

1. The algorithm will produce a different output depending on the specific secret key being used at the time. The exact substitutions and transformations performed by the algorithm depend on the key. 2. When using symmetric encryption it is very important to keep the algorithm secret. 3. On average, half of all possible keys must be tried to achieve success with a brute-force attack. 4. Ciphertext generated using a computationally secure encryption scheme is impossible for an opponent to decrypt simply because the required information is not there. 5. Monoalphabetic ciphers are easy to break because they reflect the frequency data of the original alphabet.
