Trust, and Privacy in 6G Wireless Systems, 8-12 December 2025, Taipei, Taiwan
Modern developments in mobile communication networks pose challenges for
the overall security of these systems. First, networks adopt the O-RAN
architecture and its interface specifications, which allows to deploy
third-party applications within the network. These applications may execute
untrusted code or expose additional attack surfaces. Second, joint
communication and sensing introduces environmental information as a new
data type that is processed within the network, presenting new privacy
challenges. Third, to improve energy efficiency, specialized accelerator
hardware is deployed for use cases such as artificial intelligence. Sharing
such hardware securely amongst running workloads requires advanced
isolation mechanisms. To address these challenges, we evaluate the suitability of the M³
platform for radio signal processing workloads. M³ is a hardware/software
co-designed system architecture with hardware-integrated isolation
mechanisms. In this paper, we answer the question how the overheads
introduced by the M³ hardware isolation mechanisms impact the latency of
signal processing workloads.
