Arqit’s QuantumCloud™ product can save 58% energy



A new academic study confirms that using Arqit’s software can reduce energy consumption by 58% compared to alternatives

LONDON, Nov. 11, 2022 (GLOBE NEWSWIRE) — Arqit Quantum Inc. (Nasdaq: ARQQ, ARQQW), a leader in secure quantum encryption, supported a recent study by Dr. Basel Halak and Dr. Yildiran Yilmaz of the University of Southampton and d’Arqit Chief Cryptographer, Dr. Daniel Shiu, called the benchmarking of energy costs of security applications based on asymmetric and symmetric encryption by comparing the energy consumption between asymmetric and symmetric key applications. The study confirms that Arqit’s technology can reduce the carbon footprint of operationally deployed crypto.

Forecasters (A. Andrae and T. Edler) predict that communication technologies will contribute up to 23% of global greenhouse gas emissions in 2030. The looming quantum threat requires quantum encryption solutions to protect data against this disturbing cyberthreat. While these solutions are urgently needed to protect our communications technology, they are also known to be computationally intensive and therefore power-hungry.

The academic study found that the global adoption of symmetric key systems could save 58% energy compared to the energy required for asymmetric encryption alternatives. So, as the migration to quantum secure encryption begins, Arqit’s symmetric key agreement offers the environmentally superior alternative, in addition to being the only method with independently verified proof of security on the market demonstrating zero-confidence provable quantum security.

Arqit Founder, President and CEO David Williams said“Arqit’s mission is to protect the data of our governments, businesses and citizens. Recently published security evidence demonstrates that Arqit is uniquely positioned to do so. Our customers also tell us that they care about the impact of their operations on the environment and with some of them being among the largest cloud providers, small improvements make sense. 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 contribute to this mission while also becoming proven quantum safe.

About Arqit

Arqit provides a platform as a single secure quantum encryption service that secures the communication links or data-at-rest of any networked device or cloud machine against current and future forms of attack, even from a quantum computer. Arqit’s product, QuantumCloud™, allows any device to download a lightweight software agent, which can create encryption keys in partnership with any number of other devices. The keys are computer-secured, optionally single-use and trustless. QuantumCloud™ can create unlimited volumes of keys in unlimited group sizes and can regulate secure entry and exit of a device into a group. Arqit believes it is the only company in the market to have conducted an independent assurance review of its security proof demonstrating that the software can produce zero-trust, security-proven encryption keys, i.e. permanently sheltered from attack, even from a large-scale quantum computer. This review was conducted by the GCHQ Accredited Center of Excellence In Cyber ​​Security at the University of Surrey. The addressable market for QuantumCloud™ is each connected device. Arqit recently received the Innovation in Cyber ​​award at the National Cyber ​​Awards.

Dr. Basel Halak is Director of the Embedded Systems and IoT Program at the University of Southampton, Visiting Scholar at the Technical University of Kaiserslautern, Visiting Professor at the Kazakh-British Technical University, Industrial Fellow at the Academy Royal Engineering, and a National Teacher of Advance Higher Education (HE) Academy. Dr. Halak’s publications include over 100 peer-reviewed conference and journal papers and the author of six books on the safety and reliability of electronic systems, including the first textbook on physically uncloneable functions. His research expertise includes safety evaluation of hardware devices, development of appropriate countermeasures, development of mathematical formalisms of reliability issues in CMOS circuits (e.g., crosstalk, radiation, aging) and the use of fault tolerance techniques to improve the robustness of electronics. systems against such problems. Dr. Halak lectures on digital design, secure hardware and cryptography, supervises several MSc and PhD students. He also directs the European Master in Embedded Computing Systems (EMECS), a two-year course organized in collaboration with the University of Kaiserslautern in Germany and the Norwegian University of Science and Technology in Trondheim (electronics and communication). Dr. Halak sits on several technical program committees such as HOST, IEEE DATE, IVSW, ICCCA, ICCCS, MTV and EWME. He is associate editor of IEEE access and editor of IET circuit devices and system journal. He is also a member of the World Wide Web Consortium (W3C) Hardware Security Working Group.
