“…However, the presence of tight resource constraints, including limited communication bandwidth and computational resources, and strict timing requirements for system safety and performance, makes it difficult or even impossible to add those security mechanisms after the initial design stages, without violating the system constraints or impeding the system performance [57], [58]. In [59], a general security-aware design methodology is proposed to address automotive security from early design stages, with the consideration of stringent timing and resource constraints.…”

“…The second is to develop formulations and algorithms to effectively explore the design space for optimizing design objectives while meeting all design constraints (which are often in conflict and require careful trade-offs). In [6], a Mixed Integer Linear Programming (MILP) approach is proposed to address security together with other metrics during the design stage for CANbased automotive systems.…”

“…It is critically important to address these protocols, as they are being increasingly adopted in various safety-critical systems such as automotive and avionics electronic systems for their more predictable timing behavior. Compared with priority-based networks such as CAN, TDMA-based systems have fundamental differences on system modeling (in particular for latency modeling), on security mechanism selection (global time is available for security reasons), on design space (network scheduling is the focus of this work but not a factor in [6]), and on algorithm design (MILP is not suitable for this work because of modeling complexity). Therefore, the approaches for priority-based systems such as [6] do not apply to TDMA-based systems.…”

Abstract-Cyber-security has become a critical issue for realtime distributed embedded systems in domains such as automotive, avionics, and industrial automation. However, in many of such systems, tight resource constraints and strict timing requirements make it difficult or even impossible to add security mechanisms after the initial design stages. To produce secure and safe systems with desired performance, security must be considered together with other objectives at the system level and from the beginning of the design. In this paper, we focus on security-aware design for Time Division Multiple Access (TDMA) based real-time distributed systems. The TDMA-based protocol we consider is an abstraction of many time-triggered protocols that are being adopted in various safety-critical systems for their more predictable timing behavior, such as FlexRay, TimeTriggered Protocol, and Time-Triggered Ethernet. To protect against attacks on TDMA-based real-time distributed systems, we apply a message authentication mechanism with time-delayed release of keys, which provides a good balance between security and computational overhead but needs sophisticated network scheduling to ensure that the increased latencies due to delayed key releases will not violate timing requirements. We propose formulations and an algorithm to optimize the task allocation, priority assignment, network scheduling, and key-release interval length during the mapping process, while meeting both security and timing requirements. Experimental results of an automotive case study and a synthetic example show the effectiveness and efficiency of our approach.
