Objectives of Cryptographic Protocols
Cryptographic protocols are designed to fulfill several security objectives:
- Confidentiality: Prevent unauthorized access to sensitive information during transmission or storage.
- Data Integrity: Ensure that messages or data have not been tampered with during transmission.
- Authentication: Verify the identities of parties involved in communication.
- Key Exchange: Securely distribute cryptographic keys between parties in a system.
- Non-repudiation: Prevent denial of actions, such as sending or receiving messages, by ensuring digital signatures or proofs.
