A new academic study confirms that the use of Arqit’s software can reduce energy consumption by 58% compared with alternatives

Arqit Quantum, a leader in quantum-safe encryption, supported a recent study by Dr Basel Halak and Dr Yildiran Yilmaz of Southampton University and Arqit Chief Cryptographer Dr Daniel Shiu called

comparing the energy consumption between asymmetric and symmetric key applications. The study confirms that Arqit’s technology can reduce the carbon

footprints for operationally deployed cryptography.

Forecasters (A. Andrae and T. Edler) predict that communication technology will contribute up to 23% of the global greenhouse gas emissions in 2030. The imminence of the quantum threat requires quantum encryption solutions to safeguard data against this ominous cyber threat. While these solutions are urgently needed to protect our communication technology, they are also known to be computationally intensive, hence energy demanding.

The academic study found that global adoption of symmetric key systems could save 58% of energy in comparison to the energy required for asymmetric encryption alternatives. So as the migration to quantum safe encryption begins, symmetric key agreement from Arqit offers the environmentally superior alternative, as well as being the only method with independently verified security proof in the market demonstrating zero trust provable quantum safety.

Arqit Founder, Chairman and CEO David Williams, said: “Arqit’s mission is to keep safe the data of our governments, enterprises and citizens. The Security Proof published recently demonstrates that Arqit is uniquely well positioned to do this. Our customers also tell us that they care about the impact of their operations on the environment and since some of them are amongst the biggest cloud vendors, small improvements are relevant. As world leaders at COP27 this week consider how to transition to a low carbon economy it is relevant that we can help our customers to contribute to this mission whilst also becoming provably quantum safe.”
