FOSTER ITS Report Summary

Project ID: 641492
Funded under: H2020-EU.2.1.6.

Periodic Reporting for period 1 - FOSTER ITS (First Operational, Secured and Trusted galilEo Receiver for ITS)

Reporting period: 2015-01-01 to 2016-06-30

Summary of the context and overall objectives of the project

"Increasing trust in positioning and timing (P&T) information are gaining importance in particular with the advent of connected, self-driving vehicle as well as for applications relying on GNSS to charge users. Indeed, growing interest in GNSS security is linked to the proliferation of GNSS spoofing experiments. Recent evolution of Software Defined Radio (SDR) technologies and availability of low cost SDR board provide easy and affordable solutions to counterfeit GNSS signal in real-time. Low cost GNSS spoofing devices can nowadays be procured and be used by amateurs with little technical background. Detecting and mitigating GNSS attacks is therefore required to limit and control the impacts of forged GNSS information in many applications.

Launched in January 2012, the FP7 TACOT project, supported by EC/GSA and coordinated by FDC, demonstrated the capacity to use GNSS data as a secure and trustworthy source of Position, Velocity and Time (PVT) information, paving the way towards future trusted GNSS receivers. The TACOT Proof Of Concept (POC) was demonstrated through the integration of the function into one of the most stringent ITS applications: a Digital Tachograph (robustness of "Trusted PVT module" was successfully tested in 2014 by the JRC).

Leveraging on this, FDC, STMicroelectronics together with Novacom Services and Navcert combined their efforts and started the H2020 FOSTER-ITS project in 2015. The aim is was to mature the TACOT POC and to design and develop the first secured and resilient GNSS module including authentication capability and advanced security features with commercialization perspectives just after the project end."

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

Four groups of activities were undertaken:
- Module specifications, design and development,
- Studies in view of Module certification,
- Preparation of commercial exploitation of the Module,
- Dissemination and communication.

Specification, design and development (Hardware and Software):

The FOSTER-ITS Module is conceived as a two-in-one device that embeds in a single casing, a GNSS chipset and secure MCU technologies. The module will be Galileo, GPS, GLONASS, BeiDou and SBAS enabled and will offer greater resilience against the increasing range of GNSS threats by:
- Detecting signal attack attempts and identifying the type of attack;
- Providing indicators to users about confidence of the P&T;
- Providing proof of integrity and origin of the PVT data;
- Adding secure MCU to increase speed and robustness of security functions and ensure easiest security evaluation;
- Implementing Galileo OS NAV Message Authentication capability.

The first step of the module development consisted in specification, design and development of a representative breadboard of the final module but freed from the hardware integration constraints. It has been used to:
- Evaluate all the functionalities and performances of the components and chipsets to be implemented in the module,
- Validate the module design in particular the schematics and PCB routing,
- Provide an easy way to test and debug the hardware on a large size board including high number of test points,
- Provide a board allowing to early start the module firmware development.

8 breadboard samples have been manufactured in two runs, tested and are fully operational.

Based on the breadboard return on experience, the second step consisted in module specifications and design. Main challenge was to reduce the breadboard size by 20 to obtain a compact electronic component easily integrable. Manufacturing of the first five module samples (prototype version) was launched in 2016.

The third step focused on the module test board development for which the design was completed during summer 2016.

The firmware design and development has progressed in parallel to the hardware development. Firmwares included firmwares for GNSS Part, for Secure Part, tests firmware and test tools softwares. A first stable version of the firmware for the GNSS part including detection of signal attacks attempts, calculation of Level Of Confidence (LOC) indicator on positioning information was completed as well as related tests software. Firmware for the secure part is still under development. Several test tools software have been developped including jamming and spoofing generation, record and replay of GNSS and CAN data.

Hardware and firmwares developed during first period validate the concept and the product is able to detect all the attacks described during the specification phase. Next step will strengthen the stability of the code and add the security features that ensure the possibility of easy industrialized production.

Module Certification Preparation

FOSTER-ITS module integrate advanced secure MCU technologies and GNSS chipsets with the ambition to target both automotive grade and security evaluation. An analysis of the impacts of standards for security aspects (Common Criteria) and for functional safety of road on the FOSTER-ITS System development process (technical & procedural requirements) has been conducted. Comparative analysis of the standards showed no conflicting issues. Next initiated activities focus on preparing the test framework in view of the prototypical certification activities.

Preparation of the commercial exploitation of the Module

In view of the commercial exploitation of the FOSTER-ITS module, the market study and business and exploitation plan have been consolidated. Business environment and trends has been studied. Industry potential participants and competition have been analyzed. Market segmentation has been refined and a preliminary definition of the product portfolio achieved. Two main business models are considered: selling modules to ITS integrators and operators and selling licensed IPs.

Dissemination and communication activities

Dissemination Plan was defined with team working on marketing and commercialisation. Outcomes include project logo, dedicated flyer, technical article and various slide presentations promoting the project. Several major congresses were attended (e.g. ION GNSS 2015, ITS World Congress 2016, 8th Automotive World Technical Conference, European Space Solutions 2016). In addition dedicated meetings were set-up with potential users and customers.

In conclusion, at mid-term the project is on tracks and enabled to launch in June 2016 the manufacturing process of the first five FOSTER-ITS module samples (prototype version). No major issue or risk has been identified for the next phase. All problems encountered so far have been managed or are under control.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

FOSTER-ITS module integrates for the first time in a single casing, advanced secure MCU technologies and GNSS chipsets to target both automotive grade and security evaluation. The module aims to become a design reference for secure GNSS Rx, able to respond to the spoofing / jamming threats but also to secure the whole chain from the PVT computation to the operational usage. FOSTER is clearly driven by innovation; it follows state-of-the-art electronic implementation (high integration, small footprint, MEMS sensors integration, GNSS and secure MCU in a single module) but also implements innovative features such as Galileo OS Authentication, LOC in the GNSS data, digital signature of the computed PVT, advanced dead reckoning function.
