VE-ASCOT - Advanced Security for Chains of Trust


Forging the Links for a Digitally Secure and Sovereign Value Chain in Electronics

Trust keeps the fabric of our society together, but trust is also the most fragile and transient asset we have. In the heavily interconnected and complex world of modern industry, who and what to trust has become the question that will determine the success or failure of our digital future.

Objectives and Approach

The VE-ASCOT project was initiated to develop a dedicated Chain of Trust platform for one of the most sensitive areas of industry: The production of semiconductor components. As semiconductors are ubiquitous in modern life from everyday devices to critical infrastructure, the ability to tamper with their production would offer attackers – be they unscrupulous commercial competitors, criminals, or even state actors – a means of targeting virtually any aspect of our economic, social, and political existence.

As part of the federal initiative for trustworthy electronics ZEUS, VE-ASCOT contributes to the ambitious vision of technological sovereignty by helping shore up and secure this most critical field by linking together the electronics value chain with a durable and reliable chain of trust to achieve real security-by-design.

Innovations pursued by the initiative

Every link or “record” in the proposed Chain of Trust represents one piece of the component’s identity and is secured with cryptographic methods to guarantee integrity and authenticity over the entire product lifecycle. This is achieved by embedding the records of trust in a tamper-proof repository of sensitive data together with a trust anchor to build a unique digital ID (DID) for the electronic component.

New identity markers like “physical, obfuscated keys”, sensor data, or novel, cutting-edge features will complement new building blocks of hardware characteristics to identify a special electronic module.

With such trustworthy elements in place, electronic modules in the system can prove that they are who they say they are, that they have not been tampered with, and that they are authorized to do what they are doing.

With the unobtrusive nature of the physical elements, the Chain of Trust is easily integrated into existing production and operations landscapes, including the highly automated systems that are common in semiconductor production. Cleverly integrated with new commissioning and updating procedures, the system is designed to leave no loopholes for would-be attackers.

Evaluation and Demonstration

  • The evaluation of the achieved results, their comparison to a TPM solution, and an examination of a RiscV integration form the conclusion of the research phase.
  • A platform for image processing in medical technology is used for the demonstration that displays all project results as part of a multi-stage Trusted Boot process.
  • Another demonstrator from the industrial sector is intended to show the individual features from the purchased feature kit specifically in use with systems with fewer resources in terms of performance and energy.

Revisionone Engineering GmbH

Subcontractor of Wibu-Systems
Grossrosseln, Germany

RevisionOne Engineering GmbH was founded at the beginning of 2007 by Dr. Martin Mörz and Dipl.-Ing. Marc Colling. This was preceded by two years of successful cooperation between the two independent development offices “Dr. Martin Mörz - Hardware and Software Development” and “MaCo-Engineering - Dipl.-Ing. Marc Colling”. The main focus of the engineering services is the development of complex hardware designs for high-end SoC/FPGA systems, which are used in critical infrastructures such as in the fields of medical and aerospace technology, and the associated FPGA design as well as firmware and software. By using advanced simulation software, RevisionOne can mitigate design risk even before prototypes are produced. This includes 2D and 3D Electromagnetic Field Simulation, SPICE tools, FPGA simulation tools, and mathematical modeling and simulation tools.

RevisionOne Engineering has also been working with leading semiconductor manufacturers and distributors for many years. This includes holding pan-European seminars for engineers hosted by the semiconductor manufacturers.
