🚀 [Course Title] Computer Network Security Protocols And Techniques

🎓 [Headline] Public-Private Key Cryptography, Hash Functions, End Point Authentication, TLS/SSL, IPsec in VPNs, Integrity Protection

🌍 Introduction to Computer Network Security: In this course, we embark on a journey through the intricate world of Computer Network Security. We'll explore the essential concepts and the players involved – from our trusted friends Alice and Bob to the cunning adversary Eve. Understanding their roles will set the stage for mastering the security protocols that protect our digital communications. 🛡️

🚀 [Principles Of Cryptography] Dive into the fundamental terminologies of cryptography and discover the difference between Symmetric Key Cryptography (where everyone shares a key) and Public Key Cryptography (where each user has a unique private key and a public key). We'll also take a nostalgic look at traditional ciphers, with examples like the Caesar Cipher for symmetric key cryptography and transposition ciphers.

🔑 [The Modern Ciphers] Explore the robust world of modern ciphers, including the widely used Data Encryption Standard (DES) and its enhanced version Triple DES, as well as the Advanced Encryption Standard (AES). We'll also cover various modes of operation for block cipher, like ECB, CBC, CFB, and OFB.

🔗 [Protocols in TLS/SSL] Understanding the cryptographic protocols used in TLS/SSL is crucial for securing web communications. We'll break down the handshake process, cipher suites, and the record protocol, providing a clear picture of how data travels securely across the internet. A practical TLS flow diagram will help you visualize the entire process.

🌐 [Virtual Private Networks (VPNs) with IPsec] IPsec, a set of protocols for securing internet communications, is at the heart of VPN technology. Learn about the security services provided by IPsec, including the Internet Key Exchange (IKE) – Phase 1 and Phase 2, Authentication Header (AH), and Encapsulating Security Payload (ESP). We'll also discuss the four modes of IPsec to ensure your data remains confidential and secure when tunneled through a VPN.
