CROSSCON – Cross-platform Open Security Stack for Connected Devices
1st November 2022 – 31st October 2025 | News
CROSSCON is a European Union-funded project focused on developing an open, modular, and vendor-independent IoT security stack. Running from 1st November 2022 to 31st October 2025, the project aims to address the challenges posed by the proliferation of diverse IoT devices by ensuring essential security services across heterogeneous hardware architectures.
Objectives of CROSSCON
The primary objectives of CROSSCON include:
- Developing an Open IoT Security Stack: Design a new open, modular, highly portable, and vendor-independent IoT security stack capable of running on a wide range of devices with heterogeneous hardware architectures.
- Enhancing Trusted Execution Environments (TEEs): Improve and enrich traditional trusted services offered by existing TEEs to ensure a high level of assurance across entire IoT systems.
- Ensuring Interoperability: Provide a unified set of APIs to utilize TEE functionalities and trusted services, overcoming interoperability issues among diverse IoT devices.
- Validating in Real-world Scenarios: Demonstrate the effectiveness of the CROSSCON stack through use cases in sectors such as agriculture, where secure remote attestation on agricultural UAVs is a focus.
Proposed Solutions
CROSSCON proposes the development of a new IoT security stack that is open, modular, and highly portable, ensuring vendor independence and compatibility across various hardware architectures, including ARM and RISC-V. This stack aims to enhance traditional trusted services by integrating improved Trusted Execution Environments (TEEs), thereby providing a high level of assurance across entire IoT systems. To address interoperability challenges, CROSSCON will offer a unified set of APIs, facilitating seamless utilization of TEE functionalities and trusted services across diverse devices.
Tools Developed in CROSSCON
The CROSSCON project encompasses several innovative tools and services, including:
- Security-Enhanced RISC-V System-on-Chip (SoC): Development of a RISC-V based SoC with extended hardware security guarantees to support the CROSSCON stack.
- Trusted Toolchain for TEEs: Creation of a trusted toolchain to ensure the security and reliability of applications running within Trusted Execution Environments.
- Secure Remote Attestation Mechanisms: Implementation of secure remote attestation methods, particularly for use cases like agricultural UAVs, to verify the integrity and authenticity of devices within IoT ecosystems.
