Appendix 02 · General information about the website

This appendix describes the companion website and explains how it relates to the SpringerBrief. It clarifies that the official version of record for the book is hosted by Springer, while cryptography.study provides author-maintained supplementary material, local access links, and additional context for readers.

The material helps readers navigate the book's supporting resources. It points to chapter PDFs, appendix PDFs, stable URLs, and topic-specific pages that expand on QKD, RKD, MKD, hardware, protocols, deployment, and logistics. The appendix is therefore primarily a map of the website's structure and intended use.

The distinction between official book content and supplementary author-maintained material is important. This appendix makes that boundary explicit so readers can cite the Springer book when referring to the published work and use the companion pages for additional technical and practical background.

  • Explains the purpose of cryptography.study
  • Separates Springer book material from companion resources
  • Orients readers to chapters and appendices
  • Provides stable access paths for supplementary material
  • Clarifies citation and version-of-record boundaries
