SECREDAS (Product Security for Cross Domain Reliable Dependable Automated Systems) is an European funding project with the aim to increase security, safety and privacy across the application domains road, rail and health. The purpose is to enhance the consumers' trust in connected and automated transportation and medical industries. For this, 70 partners from 16 countries - well balanced in research, industry and public sectors - collaborate to maximize the available expertise and generate application-specific solutions based on common technology elements.

The SECREDAS project started in May 2018 and will end in April 2021. It has received funding within the Electronic Components and System for European Leadership Joint Undertaking (ECSEL JU) in collaboration with the European Union's H2020 Framework Program (H2020 / 2014 - 2020) and National Authorities, under grant agreement n° 783119.

STACKFORCE is very proud to be a partner of the SECREDAS project since January 2019. We bring in and extend our long-term experience in developing innovative embedded software and network solutions to help taking the next step towards secure automated systems.



The SECREDAS project is structured in eleven work packages, which build upon each others achievements. STACKFORCE's contribution has a main focus on WP 3 - Common Technology Elements, whereas there are participations in other work packages as well due to the connection of requirements and synchronizations.

SECREDAS Structure


The main objectives of WP 3 - Common Technologoy Elements are to develop and validate a number of common technology elements for the reference architectures and to develop a framework for multi-concerned security-saftety verification and testing. Common technology elements will be provided / enhanced and design patterns created to support the development of technical security measures, maintaining functional safety, privacy and operational performance.

STACKFORCE's main tasks within WP 3 are:

Task 3.1: Common Technology Element Improvements

This task supports the objective of developing a number of Common Technology Elements (CTEs) for the reference architecture. The technical solutions solving similar problems in the different domains are gathered, adapted and - if necessary - newly developed cooperatively by partners having their main expertise in different industries. These CTEs are not limited to concrete implementations but can also contain best practices and protocol specifications.

STACKFORCE is contributing to the following CTEs:

  • CTE-01: Key-Distribution Protocols
  • CTE-08: Authentication and Authorization
  • CTE-12: Firewall
  • CTE-14: Security Testing Framework
  • CTE-16: Transport-Layer Security
  • CTE-17: OTA-Updates

Task: 3.2: Development of Design Patterns

This task describes the specifications of design patterns for development of safety, security and privacy solutions for the SECREDAS domains. Based on technology developments and concepts from other application fields, which already apply advanced security and privacy methods (e.g. IT-sector), and Common Technology Element (CTE) developments from SECREDAS.

The design patterns are one of the main outcomes of WP3, which will be used from other work packages (WP4 - WP 8) of the SECREDAS project. They describe mainly the application of CTEs, developed in Task 3.1.

Furthermore, an important relation is that between design patterns and the technical reference architecture. The technical reference architecture is an output of WP2 and gives an overview about main components and their interrelations within automated systems with focus on SECREDAS domains.

STACKFORCE has set up several sub-projects connected to the different CTEs within this tasks:

  • Secure commissioning for low power networks and devices:
    Ensuring the security level between an application server and LoRaWAN® devices during the commissioning process
  • Secure serial interface for API transport protocol (Secure SATP):
    Enhancing the serial communication protocol with more security features
  • Test System:
    Enabling the testing and verification of the robustness, correct functionalities and security of communication systems
  • TLS libraries evaluation for low power embedded devices:
    Researching the available TLS libraries at the market to understand the benefits and drawbacks of each library and to find a suitable one for the low power embedded devices
  • Firmware update over the air (FUOTA) and flexible firmware update management (ffuMgmt):
    Providing a newer firmware version to low power wireless network devices when the device has already been deployed


In summary, STACKFORCE has created several subprojects to improve the SECREDAS CTEs listed above. At the current state, we have made good progress in CTE development, as all projects already have first concepts and some of them already have first prototypes. We plan to create single demonstrators for each CTE to be integrated later at WP9. During this period, we are still looking for further opportunities to enhance the existing implementation if possible. STACKFORCE already gained first valuable knowledge regarding energy efficiency for extended security approaches for wireless communication networks, whereas the results are not satisfying yet, since it's not fulfilling known requirements to energy efficient sensors. Currently one approach is being evaluated in order to optimize communication sequences and to reduce the need for energy for this extended security, majorly affecting the key distribution.

In the STACKFORCE domain, not only the safety, security and privacy factors are considered. We have added the low power capability and wireless network factors into consideration as well. Although in automotive domain there are several kinds of device types and networks that some do not need to take care about these two factors. In any case, the focus on low power capability and wireless networks will be applicable for the vehicle sensing units, traffic sensors, vehicle monitoring system etc., which are still part of the automotive domain. We strongly believe that our contributions will provide positive results to the SECREDAS project and partners.
