Across

1. A type of encryption where each letter in the plaintext is replaced by a different letter or symbol

2. The study of analyzing and breaking encryption schemes

3. A type of encryption where the order of letters in the plaintext is rearranged

4. The process of recovering passwords from data that has been stored or transmitted in an encrypted or hashed form.

5. A method of attempting to gain unauthorized access to a system by systematically attempting all possible combinations of words from a dictionary as passwords.

6. A type of attack where the cryptanalyst has access to both the plaintext and its corresponding ciphertext

7. A method used in cryptography to try all possible combinations until the correct one is found

8. A technique used in cryptanalysis to analyze the frequency of letters or symbols in a ciphertext

Down

9. A precomputed table used in password cracking to reverse cryptographic hash functions and quickly determine the original password.

10. A security feature that locks a user's account after a specified number of failed authentication attempts.

11. A measure of the effectiveness of a password in resisting unauthorized access.
