cryptographic protocols

Cryptographic protocols are systematic methods used to secure communication and protect data through encryption. They establish rules for how information is transmitted, ensuring that only authorized parties can access or understand it. These protocols can verify identities, keep messages confidential, and ensure data integrity. Common examples include HTTPS for secure web browsing and SSL/TLS for secure email. By using cryptographic protocols, individuals and organizations can safeguard sensitive information from unauthorized access and cyber threats, promoting trust and privacy in digital interactions.
