Quantum Risks and Rewards: Forward-Defending Cybersecurity

Quantum computers are in their infancy but rapidly advancing, so firms need to upgrade security protocols now to address threats that quantum technology could one day pose to current cryptographic methods, said Clement Jeanjean, business operations lead in the quantum security group at SandboxAQ.

"The risk is that when these quantum computers are developed fully and operate at the required scale, parts of cryptography could be broken by them," Jeanjean said. The real danger lurks in the potential of malicious actors capturing properly encrypted data now and decrypting it later when they gain access to advanced quantum computers, he said.

Jeanjean advises security professionals to commence planning for the future and to migrate from existing cryptographic standards to quantum-resistant cryptography. "Whether quantum computers come or not, the train has left the station - from the regulators, from the industry, from the cryptographic community," he said. "The advent of fully functional quantum computers could unravel the cryptographic systems in place today, emphasizing the need for preemptive measures and innovations in quantum-resistant cryptographic standards."

In this video interview with Information Security Media Group at the ISMG London Cybersecurity Summit, Jeanjean discussed:

• The role of cryptography in securing sensitive data and potential risks from advancements in quantum computing;
• The projected timeline for quantum risks to materialize and the need for proactive preparation and adaptation;
• The evolution and implementation of quantum-resistant cryptographic standards.

Jeanjean has a wealth of experience in tech entrepreneurship. He has co-founded four tech companies, and two of them have been acquired. Prior to his current role, he served as the COO of Cryptosense. Specializing in devising go-to-market strategies and innovation, Jeanjean has delivered multimillion-dollar deals across diverse industries including banking, automotive and health sciences. He also lends his expertise to startups and large companies, advising them on innovation and entrepreneurial projects.
