Appendix 01 · Abstract and Summary
This appendix provides a compact abstract and summary of the book's overall argument. It introduces the central comparison between QKD, RKD, and MKD and explains why the authors evaluate these methods together: all three address key generation or distribution under high-security assumptions, but each depends on different physical, technical, and organizational conditions.
The summary emphasizes that QKD derives its promise from quantum effects, RKD from reciprocal radio-channel properties, and MKD from physical transport of high-capacity key media. It also shows that each method has different limits: QKD is infrastructure-heavy, RKD is range- and rate-limited, and MKD creates logistics and chain-of-custody requirements.
The appendix is useful as a short orientation before reading the full book or the detailed supplementary material. It frames the work as a practical decision aid for procurement and architecture rather than as a purely theoretical comparison of cryptographic ideas.
