This week, the head of GCHQ raised the alarm about advanced cyber actors targeting the West’s critical infrastructure. This is not another headline—it's a wake-up call. Threats to our digital and physical systems are real, and the stakes couldn't be higher. From power grids to transportation networks, the potential for disruption is enormous.
Preventing today’s advanced threats requires a data centric view on security: providing multiple layers of security on information assets that matter the most. While difficult to implement, especially in large organizations, these techniques are widely discussed and well-understood.
Complicating matters further, a technological revolution is on the horizon. While many experts have been careful in raising the alarm on the threats of quantum computing to the internet, the sentiment is shifting.
“I think today the message needs to be: yes, unequivocally, worry about this now. Have a plan.” says Scott Aaronson.
From people like Aaronson at the forefront of quantum computing research, this speaks volumes.
Protecting tomorrow with tools today
While quantum technology promises breakthroughs in medicine and logistics, it also has the potential to make widely-used forms of encryption obsolete, exposing sensitive data. This dual reality demands a forward-thinking approach to cybersecurity.
Protecting sensitive information requires tools that are not only secure by today's standards but also resilient against tomorrow's challenges. It's not enough to focus on current threats—as Aaronson indicates, preparing for a post-quantum internet must start now.
Fortunately, standardization efforts are well underway to provide the building blocks to secure the post-quantum internet. Standardization addresses data in transit, hash-functions and digital signatures. The National Institute of Standards and Technology (NIST) has published three standards for post-quantum cryptography. More recently, the Dutch AIVD released a handbook on post-quantum migration.
Encrypted computing solutions, based on information theoretic cryptography primitives, also prove immensely valuable for protecting data at rest and in use.
Data platforms like Roseman Labs, designed with cutting-edge encryption are planning for a post-quantum world. These systems ensure sensitive and vital information can be exchanged, stored and used securely, even against a quantum-capable adversary. By adopting these advanced technologies, governments, businesses, and critical infrastructure operators can stay one step ahead.
Technology alone isn’t the answer
A comprehensive strategy for post-quantum security is essential: investing in knowledge, fostering international collaboration, and committing to pioneering innovation. As cyber threats grow more sophisticated, so too must our defenses.
We should assume that the quantum era is an approaching reality. By embracing the tools and strategies of tomorrow, we can protect the systems that power our lives and safeguard our collective future today.
