This study introduces a secure framework for 3D printing devices using post-quantum cryptography and subnet hopping on Controller Area Network (CAN) buses. It enhances security against data manipulation and hardware Trojans, improving authentication efficiency.

Area of Science:

  • Engineering
  • Cybersecurity
  • Manufacturing Technology

Background:

  • The increasing use of 3D printing (additive manufacturing) in critical sectors like defense and medicine necessitates robust security measures.
  • The rise of quantum computing poses future threats to existing cybersecurity protocols, particularly for Industrial Internet of Things (I-IoT) devices.
  • Adversarial data manipulation on communication buses like Controller Area Network (CAN) presents a significant attack surface.

Purpose of the Study:

  • To propose a novel, secure framework for Controller Area Network (CAN)-based additive manufacturing (AM) devices.
  • To address the security challenges posed by adversarial data manipulation and the advent of post-quantum computing.
  • To enhance the protection of AM devices and their networks against hardware Trojans and other threats.

Main Methods:

  • Development of a hierarchical tree security framework utilizing subnet hopping between isolated CAN buses.
  • Implementation of a post-quantum-supported security solution for CAN-based AM systems.
  • Physical implementation and timing benchmarks of the proposed framework's communication and authentication schemes.

Main Results:

  • The proposed framework demonstrates significant improvements in message authentication costs compared to existing solutions.
  • Achieved 25% and 90% improvement in message costs for authentication against lightweight and post-quantum CAN security solutions, respectively.
  • Timing benchmarks confirmed the efficiency of the normal communication (hopping) and authentication schemes.

Conclusions:

  • The novel framework provides a secure, post-quantum-ready solution for additive manufacturing (AM) devices on CAN buses.
  • Subnet hopping allows for plug-and-play compatibility with legacy devices while minimizing the attack surface.
  • The framework offers a robust defense against data manipulation and hardware Trojans in critical supply chains.
