Chapter 5: CRYPTOGRAPHY
This chapter examines the security services required to protect information and systems against intentional threats. These services—confidentiality, integrity, availability, authentication, and non-repudiation—form the foundation of modern cybersecurity architectures. Cryptography provides the mathematical tools that enable these services, just as channel coding provides the tools for reliability.
