Company profile
researched Aug 2026Crypto Quantique is a London-based silicon security company that supplies low-footprint security IP and lifecycle software so that device identity, integrity and trust are anchored in hardware and maintained through manufacturing, deployment and operation. Its hardware portfolio includes analog and digital PUF IP, a lightweight root-of-trust, an agile secure element, cryptographic cores, fault-injection detection and a true random number generator. The flagship hardware product, QDID, is described as a quantum-driven hardware root-of-trust that uses quantum tunnelling in silicon to generate multiple unique cryptographic keys on demand; the company states these keys are never stored and are resistant to most side-channel attacks.
On the software side, QuarkLink is a device security and management platform covering zero-touch provisioning, secure boot, over-the-air updates, service onboarding, and fleet and certificate management, with integrations to cloud service providers. QuarkLink is sold as an independent product that works with any hardware root-of-trust, not only devices containing QDID. Together the two products are marketed as Q:Architecture. The company also positions QuarkLink as a means of accelerating compliance with the EU Cyber Resilience Act.
More recent website messaging emphasises unbundled, customisable security IP designed around a customer's boot flow, memory architecture, trust boundaries and gate-count constraints, together with security architecture validation and advisory services for silicon teams. Target design contexts include constrained SoCs and IoT, custom SoCs and chiplets, and "Physical AI" designs, with stated application sectors in medical devices, Industry 4.0 and automotive. The company says it holds multiple patents across silicon and software domains.
Founding story
Co-founders Dr Shahram Mossayebi (CEO, PhD in post-quantum cryptography from Royal Holloway, University of London) and Dr Patrick Camilleri (an ex-Philips semiconductor IC designer with an electrical engineering PhD from Otto-von-Guericke University) identified a vulnerability in existing IoT chip designs and developed QDID, described as the first proven quantum-driven secure silicon chip design. Recognising that a device is only as secure as its weakest point, they subsequently created QuarkLink to secure the rest of the supply chain. Press material from 2019 also names Kumi Thiruchelvam, a former Broadcom and platform security executive, as a co-founder who joined as chief commercial officer.
Business model
Crypto Quantique licenses semiconductor security IP blocks to chip designers and sells/offers subscription access to the QuarkLink device security and management software platform for device makers, complemented by security architecture validation and advisory engagement with silicon design teams. The website offers a free trial and demo booking for the software.
Sources describe IP licensing to semiconductor and SoC designers plus a device security software platform for device manufacturers; no pricing or revenue figures are disclosed in the sources.
Traction
Siemens selected Crypto Quantique IP for the architectural requirements of its next-generation silicon lifecycle management platform, per a company case study reference. A third-party profile cites partnerships with STMicroelectronics, Renesas, EPS Global and Macronix, and over 35 employees. Announced collaborations include Xiphera (October 2024), ZARIOT and Kigen for cellular IoT (June 2024), ADLINK Technology for industrial PCs (October 2024), and RED Semiconductor for an edge-computing microprocessor (July 2023). No revenue or customer-count figures are disclosed.
Latest developments
In April 2025 the company announced QRoot Lite, a lightweight, configurable root-of-trust IP for resource-constrained IoT devices, and published an independent cetome analysis on streamlining EU Cyber Resilience Act compliance using QuarkLink. In March 2025 it demonstrated its device security platform for CRA-compliant development at Embedded World 2025. Current website messaging focuses on unbundled security IP, security architecture validation services, and use cases spanning constrained SoCs, chiplets and Physical AI.
βΈFull profile β market position, technology, go-to-market, geography, history, risks & controversies
Market position
Crypto Quantique positions itself as a supplier of security IP and lifecycle software for security-critical silicon, claiming the world's first proven quantum-driven secure silicon chip design and differentiating its PUF approach from other PUFs it describes as vulnerable to cloning and side-channel attacks. A third-party profile places it in the IoT security and embedded systems sector alongside semiconductor ecosystem partners.
Stated differentiators are a quantum-tunnelling-based root of trust producing multiple uncorrelated, never-stored keys; security IP sized for real power, area and performance constraints rather than reference designs; a software platform (QuarkLink) that is hardware-agnostic and works with any root of trust; and a multi-patent portfolio spanning silicon and software.
Technology
QDID is a hardware root-of-trust that derives unforgeable device identities and cryptographic keys from silicon's physical properties using quantum tunnelling, generating multiple uncorrelated keys on demand without storing them. The IP portfolio adds analog and digital PUFs, a lightweight configurable root-of-trust (QRoot Lite), an agile secure element, cryptographic cores, fault-injection detection and a TRNG added to the side-channel-protected PUF block in December 2024. QuarkLink provides provisioning, secure boot, OTA updates, onboarding and certificate/fleet management, and was upgraded for post-quantum cryptography in December 2024. The company also released TuRiNG, an open-source randomness test suite for PUFs.
Go-to-market
Direct engagement with silicon design teams during the SoC design phase, plus a partner and distribution network: the company appointed IP distributors across Asia-Pacific (announced July 2024) and ITEC Limited of Tel-Aviv for Israel (July 2024), and works with ecosystem partners including Xiphera, ZARIOT, Kigen, ADLINK Technology and RED Semiconductor. It also markets via trade events such as Embedded World 2025, webinars, whitepapers and free trials of QuarkLink.
Integrated circuit designers and semiconductor companies building SoCs and chiplets, embedded developers and device manufacturers, including medical device manufacturers, industrial/Industry 4.0 users, automotive, radio module makers and industrial PC vendors.
Geography
Headquartered in London, United Kingdom (a third-party profile lists City of London). Commercial reach extends through IP distributors in the Asia-Pacific region and a representative in Israel (ITEC Limited, Tel-Aviv), with regulatory focus on EU and UK frameworks (CRA, PSTI).
History
A third-party profile records a $13K seed in September 2016 with Passion Capital and Simon Lambert. In September 2019 the company announced an $8M seed round led by ADV (Accelerated Digital Ventures) with participation from Entrepreneur First and others, and appointed Kumi Thiruchelvam as chief commercial officer and co-founder. A $7M Series A involving Parkwalk Advisors is dated July 2022 by the same profile. Product and partnership announcements followed through 2023-2025, including the RED Semiconductor agreement (2023), cellular connectivity support for QuarkLink (February 2024), the TuRiNG open-source PUF randomness test suite (August 2024), distributor appointments in Asia-Pacific and Israel (2024), a PQC upgrade to QuarkLink and TRNG addition to its PUF IP (December 2024), and the QRoot Lite root-of-trust IP launch (April 2025).
Risks & controversies
Source data is inconsistent on basic facts: one third-party profile lists a 2015 founding date and an employee band of 1001-5000 in its quick facts while its own text states a 2016 founding and over 35 employees, and it reports both $15.0M across three rounds and "over 14 million dollars" raised. The business is exposed to semiconductor design-win cycles and to regulatory timing (EU Cyber Resilience Act, UK PSTI). No litigation or controversies are described in the sources.
