Quantum computing is expected to render many traditional methods of exchanging cryptographic keys obsolete. Encryption keys that have protected confidential information from even the most powerful computers for decades could be easily broken by a cryptographically relevant quantum computer (CRQC) – and so-called Q-Day, when that computer becomes available to criminals, could be as little as 3 years away.
The rise of quantum computing is forcing organisations to rethink how they secure data. Traditional protocols for generating and exchanging cryptographic keys, such as RSA and ECDH, will soon be broken by quantum computers, leaving sensitive data vulnerable to interception.
Authenticating both human and device identities is arguably the greatest threat facing cybersecurity experts – and by extension, the organisations they work for – this decade. If an attacker is able to pose as a genuine user with access to your network and your data, the damage they can do to your organisation, and potentially to your clients and suppliers, is significant.
As quantum security efforts and innovations accelerate, the variety of technologies, protocols, standards, and algorithms can feel overwhelming. Especially because, in these early days of Post-Quantum Cryptography, the conversation is mainly being led by academics and technologists who are happy to talk in very technical terms.
Last week I had a very productive and interesting day in Seattle at Mobile Future Forward 2025. The theme this year was “quantumverse” – the convergence of a number of revolutionary technologies, including quantum computing, and its potential to transform humanity – so naturally I wanted to represent Cavero Quantum, and learn more about how people are grappling with the challenge of quantum security.
Yes. We really do.
Not just because quantum computers may one day be able to break today’s encryptions. The threat isn’t purely on the horizon. It’s here today – in intent, strategy, and preparation.
The ATIS whitepaper on quantum threats says the timeline to Q-Day is shorter than we thought. Symmetrikey can help you rise to the challenge.
Symmetrikey uses Ring Learning With Errors and Correlation Filtering to ensure quantum-safe, scalable security. Learn how in this blog.
