Cryptographic protocols are sequences of operations using cryptographic primitives to achieve security goals such as confidentiality, integrity and authentication.
Semantic Classification

- Cryptographic protocols combine primitives such as encryption, digital signatures and key exchange into structured exchanges between parties. They define message order, validation steps and the security properties expected to hold.
- Examples include key establishment, authentication and secure channel protocols. Formal analysis is used to verify that intended properties survive adversarial conditions such as message interception or replay.
