iMQ and SecuX Launch PUF Hardware Digital Signature: Defining Trustworthy DID Standards for the AI Agent Era

[March 23, 2026, Taipei] iMQ, a leading global provider of security chip solutions, today announced that its core PUF SE security chip technology has been successfully integrated into the newly released PUF Signer Dongle (SecuHSM) by its partner SecuX. In an era where AI agents and Generative Engine Optimization (GEO) are reshaping the digital ecosystem, iMQ, with Physically Unclonable Function (PUF) at its core, provides global digital content publishers with an "immutable and physically isolated" trust foundation, officially ushering in a new era of hardware-level Decentralized Identifier identity (DID).

At the heart of this technological collaboration, iMQ's SQ7191 and CQ9008 series chips (utilizing eMemory/PUFsecurity's NeoPUF IP) construct native hardware trust from chip fingerprints to undeniable signatures. Unlike traditional software encryption, this technology utilizes minute, randomly generated differences in the semiconductor manufacturing process to give each chip a unique "chip fingerprint," ensuring that the private key is generated within a secure hardware area and physically isolated, making it impossible to extract or crack.

Furthermore, NeoPUF employs innovative Quantum tunneling pressure technology, amplifying the originally minute physical differences between adjacent transistors by applying precisely controlled voltage pressure to the circuit, thus giving random feature signals higher readability and stability. This mechanism not only significantly improves the reliability of PUF response but also effectively reduces the impact of environmental variations (such as temperature and voltage fluctuations) on the identification results, ensuring long-term stability of chip fingerprints and preventing misjudgments, fundamentally strengthening the reproducibility and security of hardware trust.

Meanwhile, the private key is generated in a hardware-secure area and physically isolated, making it impossible to extract or crack. Combined with built-in firmware compliant with the PKCS#11 standard, it can seamlessly connect to CA registration mechanisms of impartial third parties such as governments, enterprises, and C2PA. Whether it's traditional KYC real-name authentication or decentralized identity (DID), both can achieve highly legally valid digital signatures through the iMQ chip.

In the new era of AI technology entering the "Lobster Agent" and GEO challenges, the cost of verifying the authenticity of information is skyrocketing. iMQ and SecuX have joined forces to empower AI agents, proposing a vision to transform trust into quantifiable assets. By equipping each AI agent with a hardware signature tool equipped with an iMQ chip, a complete trust loop of "hardware signature + blockchain ledger + star rating" is constructed.

• Traceable Source: Hardware-based signatures ensure the "non-repudiation" of digital content from its creation.
• Automated Legal Evidence Preservation: Signature logs are synchronously recorded in an immutable blockchain ledger, significantly reducing legal evidence collection and adjudication costs.
• Trustworthy DID Evaluation Mechanism: Combining public feedback and data accumulation, the system automatically assigns a "star rating" to DIDs, giving high-quality and authentic content publishers higher weight in AI search and recommendations, allowing them to gain priority in securing market trust benefits.

iMQ COO Frank stated, "In an era of AI-generated content proliferation, 'trust' should not only rely on algorithms but also be rooted in hardware. iMQ's PUF technology provides the most fundamental proof of authenticity for the digital world. Through deep collaboration with SecuX, we are not only selling chips but also assisting businesses and creators in establishing a verifiable and profitable trust system in the AI era."
