Chapter: Security Engineering And Cryptography
Cryptographic protocols and algorithms are essential for securing data across networks, applications, and storage systems. Below is a detailed exploration of key cryptographic methods, their applications, and real-world examples.
1. Cryptographic Protocols
Cryptographic protocols define rules for secure communication, ensuring data integrity, confidentiality, and authentication.
a) Secure Sockets Layer (SSL) / Transport Layer Security (TLS)
- Description:
SSL (now obsolete) and TLS secure communication over the internet, such as HTTPS. TLS is the modern standard, with versions TLS 1.2 and TLS 1.3.
