Across

1. A cryptanalysis technique that involves trying every possible key to break a cipher

2. The vertical lines of the zigzag pattern used to read off the ciphertext for the Rail Fence Cipher

3. The encrypted message produced by applying a cipher to plaintext

4. A cipher that rearranges the order of the plaintext without changing the actual letters or characters

5. The original message before being encrypted by a cipher

6. The horizontal lines of the zigzag pattern used to write the plaintext for the Rail Fence Cipher

7. Communication that is encrypted and protected from unauthorized access

8. A set of rules or steps that describe how to solve a problem or perform a task

9. The size or length of the key used by a cipher

10. The practice of analyzing and breaking codes and ciphers

11. A cryptanalysis technique that involves analyzing the frequency of letters or characters in ciphertext to identify patterns

Down

12. A cipher that encrypts a block of plaintext at a time and produces a corresponding block of ciphertext

13. The process of converting plaintext into ciphertext using a cipher

14. The total number of possible keys that can be used by a cipher

15. The process of converting ciphertext into plaintext using a cipher

16. A pattern that moves in a back-and-forth motion like a zigzag

17. A transposition cipher that rearranges plaintext by writing it in a zigzag pattern over a predetermined number of rows before reading off the ciphertext from the columns.
