cryptographic protocols

**cryptographic protocols**

Cryptographic protocols are sets of rules and procedures used to secure communication and data exchange in digital environments. They employ cryptographic algorithms to ensure confidentiality, integrity, authentication, and non-repudiation of information. Common examples include SSL/TLS for secure web browsing, IPSec for network security, and key exchange protocols like Diffie-Hellman. Understanding cryptographic protocols is essential for protecting sensitive data and maintaining trust in online systems.
