1. A substitution cipher in which each letter is replaced with a single, fixed symbol throughout the ciphertext.

2. A substitution cipher in which the symbol used to replace a letter varies depending on its position in the plaintext.

3. A graphical representation used to represent something else, such as a letter or number in a cipher.

4. The set of symbols used in a cipher to represent plaintext letters.

5. The practice of using the same key repeatedly in a cipher.

6. A sequence of steps or instructions used to solve a problem or perform a task.

7. The process of analyzing encrypted information to decipher the original message or data.

8. The process of converting ciphertext back into plaintext using a cryptographic algorithm and a key.

Down

10. The practice of securing communication from unauthorized access.

11. Also known as the Masonic Cipher, it is a substitution cipher used in cryptography that replaces letters with symbols and shapes.

12. The encrypted message or data that is the result of an encryption process.

13. A cipher that replaces each letter in the plaintext with a different letter, symbol, or number in the ciphertext.

14. The process of converting plaintext into ciphertext using a cryptographic algorithm and a key.

15. The length of the key used in a cipher, typically measured in bits.
