Across

1. A polyalphabetic cipher that uses a keyword consisting of a repeating pattern of letters to encrypt a message.

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

3. A bit depth that allows for 65,536 different colors or shades, providing a richer color representation.

4. The process of converting data into a specific format for efficient transmission or storage.

5. A unique number is assigned to each character in Unicode.

6. A group of four bits.

7. The addition of binary numbers.

8. A six-digit code used to specify colors in the RGB color model.

9. The maximum extent of vibration or oscillation in a sound wave, representing the loudness or volume of the sound.

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

Down

11. A digital image in which each pixel is represented by a single sample, representing only shades of gray.

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

13. A color scheme that represents different intensities of gray, ranging from black to white.

14. A cipher that uses multiple alphabets to encrypt a message.

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

16. The study of the frequency and distribution of letters or symbols in a text to help break a cipher.

17. A number representation system using only two digits, 0 and 1.

18. The process of converting sound waves into a digital form that can be stored or manipulated by a computer.
