Post-Quantum Cryptography: The Board-Level Migration No One Can Defer
By the Daneborg Times Technology Desk Somewhere in the next decade, a sufficiently powerful quantum computer will be able to break the public-key cryptography that protects almost everything digital — banking, government communications, medical records, the software update mechanisms inside critical infrastructure. The date is uncertain. The obligation to prepare, argues Professor Kai London , is not. “Post-quantum migration is now a board-level programme, not a research footnote,” London says. “And it is the rare cyber risk where doing nothing today guarantees you fail later. The data an attacker steals now can be decrypted the moment the hardware arrives. That is why the clock has already started.” Harvest now, decrypt later The threat London refers to has an unglamorous but chilling name: “harvest now, decrypt later.” Adversaries do not need a quantum computer today to benefit from one tomorrow. They simply capture encrypted tra...
