Chapter 9

Cryptography and Symmetric Key Algorithms

THE CISSP EXAM TOPICS COVERED IN THIS CHAPTER INCLUDE:

  • Cryptography
    • Understand the application and use of cryptography
      • Data at rest (e.g., hard drive); data in transit (e.g., “on the wire”)
    • Understand encryption concepts
      • Foundational concepts; symmetric cryptography; asymmetric cryptography; hybrid cryptography; message digests; hashing

Cryptography provides added levels of security to data during processing, storage, and communications. Over the years, mathematicians and computer scientists have developed a series of increasingly complex algorithms designed to ensure confidentiality, integrity, authentication, and nonrepudiation. While cryptographers spent time developing strong encryption ...
