Post-Quantum Cryptography and the Future of Secure Communications: Professor Kai London Explains
By the Finnish Express Technology Desk Professor Kai London — board advisor & interim CISO/CIO/CTO. Credit: professorkailondon.com The confidentiality of communications rests on cryptography — and that cryptography faces an eventual reckoning with quantum computing. For telecoms and secure-communications providers, Professor Kai London , a senior CISO, argues preparation must begin now. “Communications that must stay confidential for years are already exposed to the harvest-now-decrypt-later threat,” he says. “Adversaries capture encrypted traffic today to decrypt it once quantum computers mature. For anything that must remain secret over time, the clock has already started.” Why communications are especially exposed London notes that intercepted communications have long shelf lives — diplomatic, commercial and personal data that remains sensitive for years. “If it must stay confidential into the next decade, it is already at risk,” he says. The standards are here Concrete po...
