Quantum Deterrence: Encryption, Decryption, and the Arms Race of Math (Hardback or Cased Book)

From the moment states learned to turn intercepted signals into strategic advantage, cryptography has been more than a technical craft: it has been a way of organising power. Today, more powerful computation is reshaping that contest in distinctive ways. The risk is not only that tomorrow's machines may read today's encrypted archives, but that the mere possibility of future decryption changes what rivals collect, what institutions must protect, and how long trust can reasonably last.

Quantum Deterrence explains the strategic implications of post-quantum cryptography without treating it as a single technological cliff-edge. Kenan Durveil shows how encryption standards shift, why key management is often the true point of failure, and how "harvest now decrypt later" turns long-lived data into a reserve of influence. Moving across protocols, certificates, archives, and constrained communications, the book focuses on the institutional realities that determine outcomes: legacy systems that cannot be updated, vendors that set defaults for the world, and governance structures that struggle to own long-horizon risk.

Written for students, general readers, and policy and security audiences, the book provides a clear framework for cryptographic migration as a coordination and credibility problem. Readers finish with a sharper understanding of which systems are most exposed, why capability gaps can produce asymmetric advantage, and what deterrence can mean when secrecy may fail after the fact. The central lesson is durable: in a world where mathematics and machines keep advancing, the decisive question is whether institutions can change as quickly as the threat model does.

Kenan Durveil writes about the intersection of cryptography, institutional behaviour, and the geopolitics of technology. His work is guided by a simple conviction: security failures are rarely caused by a single flawed equation, and more often by the way organisations distribute responsibility, defer uncomfortable decisions, and inherit systems they no longer fully understand. He is interested in the places where abstract guarantees meet real-world constraints such as procurement cycles, legacy infrastructure, and the need to explain technical risk to non-technical leaders without resorting to either panic or false reassurance.Durveil approaches encryption as a civic and strategic subject as much as an engineering one. He is attentive to how standards, certification, and platform concentration shape who gets to define "secure enough", and to how intelligence incentives can quietly influence public choices about trust. A recurring thread in his perspective is the long European memory of contested communications, from wartime codebreaking to the bureaucratic infrastructures that followed, and how those histories continue to inform today's debates about secrecy, legitimacy, and verification.Quantum Deterrence reflects his commitment to clarity: making advanced ideas readable without flattening them, and treating readers as capable of grappling with uncertainty. The result is a rigorously framed, publicly intelligible account of why stronger computation changes not only what can be decrypted, but also what institutions must become to remain trustworthy.
