Cryptography and wireless security

This chapter covered how SSL/TLS uses cryptographic tools to secure data over the Internet and how the IEEE 802.11 wireless standard enforces security through authentication, encryption, and integrity

Chapter 5: Cryptography and wireless security

Chapter 5 explored the critical security mechanisms that protect data in transit, focusing on two essential areas: cryptography for online communications and security for wireless networks. It detailed how cryptographic tools—symmetric encryption (AES), asymmetric encryption (RSA), and hashing (SHA-256)—are combined within the SSL/TLS protocol to provide confidentiality, integrity, and authentication, explaining processes like the TLS handshake and the Diffie-Hellman key exchange. The chapter then applied these principles of authentication and encryption to the wireless domain, analyzing how the IEEE 802.11 standard forms a security framework and comparing the evolution of wireless security protocols (WPA, WPA2, WPA3) in safeguarding network access and data privacy.
