2. An ancient cipher technique that shifts letters in the alphabet by a fixed number.
3. The process of converting data into an unreadable format to secure it
5. A type of cryptography that uses mathematical problems as the basis for security.
8. An encryption method that uses a single key for both encryption and decryption.
11. The method of hiding a message within another message.
13. A measure of the average number of bits needed to represent a symbol in a data stream.
14. A technique that reduces the size of data for storage or transmission.

1. The process of converting encrypted data back into its original form.
