G7 Cyber Expert Group Warns of Quantum Computing Risks to Financial System

Strategic Insights

— 2 min read

The G7 Cyber Expert Group, chaired by the US Department of the Treasury and the Bank of England, has released a public statement highlighting the potential cybersecurity risks associated with developments in quantum computing. Quantum computers, scheduled to be built in the near future, will be able to solve computational problems currently deemed impossible for conventional computers to solve within a reasonable amount of time. This poses a significant threat to financial institutions' ability to secure communications and IT systems, potentially exposing financial entity data, including customer information. The G7 CEG emphasizes the importance of planning for the quantum transition to ensure economic security and prosperity.

Key Takeaways:

  • The G7 Cyber Expert Group has identified the potential cybersecurity risks associated with quantum computing to the financial system, including the ability of cyber threat actors to defeat certain cryptographic techniques.
  • The exact timeline for developing quantum computers with these capabilities is uncertain, but there is a real possibility that such capabilities could emerge within a decade.
  • The National Institute of Standards and Technology (NIST) has released an initial set of quantum-resilient encryption standards, with additional standards expected in the future.
  • Financial entities must develop a plan for mitigating quantum computing risks, assess quantum computing risks, and improve their understanding of the issue, risks, and strategies for mitigating those risks.
  • The G7 CEG recommends that financial authorities and institutions start taking steps to build resilience against quantum computing risks, such as developing internal plans, obtaining support for their successful implementation, and providing funding and other resources.
  • Todd Conklin, Treasury Deputy Assistant Secretary for Cybersecurity and Critical Infrastructure Protection, emphasizes the importance of financial institutions providing funding and other resources needed to support the implementation of quantum-resilient technologies.

Statistics:

  • Quantum computers capable of solving computational problems currently deemed impossible for conventional computers to solve within a reasonable amount of time are being built ([1]).
  • The time to start planning for quantum computing risks is now, given the potentially long lead time needed to put in place quantum-resilient technologies ([1]).
  • The National Institute of Standards and Technology (NIST) has released an initial set of quantum-resilient encryption standards last month ([1]).
  • Additional standards from NIST and other standard-setting bodies are expected in the future ([1]).
  • The G7 CEG's membership includes representatives of financial authorities across all G7 countries as well as the European Union ([1]).
