The Quantum Security Race by Kai London

Cryptographic migration is the largest technical change most organisations will not have planned for. It touches every certificate, protocol, device, contract and supplier — and the data being captured today may still be sensitive when the transition completes. The Quantum Security Race treats it as a multi-year programme and sets out how to run it.

What the book covers

Cryptographic discovery

Building and maintaining an inventory of algorithms, keys, certificates and protocols across applications, networks, devices and suppliers.

Harvest-now, decrypt-later exposure

Identifying data whose confidentiality requirement outlives current cryptography, and prioritising accordingly.

Crypto-agility by design

Architectural patterns that make the next algorithm change routine rather than exceptional.

Migration sequencing

Hybrid schemes, phased rollout, interoperability testing and rollback planning.

Supplier and product readiness

Questions to put to vendors, contractual hooks, and how to assess embedded and OT estates with long lifecycles.

Governance and reporting

Funding the programme, tracking progress and evidencing diligence to regulators and auditors.

Who it is for

CISOs and security architects, cryptography and PKI teams, financial-services and critical-infrastructure risk leaders, and boards asked to fund a transition whose deadline is uncertain.
