1. A piece of information used to authenticate a user's identity, such as a password or biometric data.
2. In asymmetric encryption, a key that is publicly available and used for encryption.
3. Implementing measures to safeguard a network against unauthorized access, improper use, alteration, or disruption of service.
4. The process of converting ciphertext into plaintext using a decryption algorithm and a key.
5. In asymmetric encryption, a key that is kept secret and used for decryption.
