Cryptographic Protocols
Cryptographic protocols are formalized sets of rules and procedures that use cryptographic techniques to secure communications, authenticate parties, and ensure data integrity and confidentiality in digital systems. They define how cryptographic algorithms (like encryption, hashing, and digital signatures) are applied in specific scenarios, such as secure web browsing, email, or network authentication. These protocols are essential for implementing security in applications ranging from online banking to IoT devices.
Developers should learn cryptographic protocols when building systems that require secure data transmission, user authentication, or protection against tampering, such as in web applications, APIs, or distributed networks. They are crucial for compliance with security standards (e.g., GDPR, HIPAA) and for preventing attacks like man-in-the-middle or data breaches. Use cases include implementing HTTPS with TLS/SSL, securing APIs with OAuth, and encrypting database connections.
