Towards Secure Time-Triggered Systems

چکیده
This paper presents the development of a novel joint safety and security architecture for dependable embedded time-triggered systems. While fault-tolerance properties of time-triggered protocols have been very well studied, research on security aspects for time-triggered systems have hardly been covered. Therefore, we explore system design principles which efficiently realize security mechanisms for time-triggered architectures. A particular focus is on synergistic effects of security and safety-related functions, thereby supporting the roll-out of safety-critical embedded systems even in ‘untrusted’ environments. As a main contribution, we present the Secure COmmunication in Time-Triggered sYstems (SCOTTY) approach to build secure time-triggered systems.

Computation and Communication Evaluation of an Authentication Mechanism for Time-Triggered Networked Control Systems
In modern networked control applications, confidentiality and integrity are important features to address in order to prevent against attacks. Moreover, network control systems are a fundamental part of the communication components of current cyber-physical systems (e.g., automotive communications). Many networked control systems employ Time-Triggered (TT) architectures that provide mechanisms ...
متن کاملSecure Communication in Shotgun Cellular Systems
In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...
متن کاملAnalysis of Applying Event-triggered Strategy on the Model Predictive Control
In this paper, the event-triggered strategy in the case of finite-horizon model predictive control (MPC) is studied and its advantages over the input to state stability (ISS) Lyapunov based triggering rule is discussed. In the MPC triggering rule, all the state trajectories in the receding horizon are considered to obtain the triggering rule. Clearly, the finite horizon MPC is sub-optimal with ...
متن کاملA time-triggered object tracking subsystem for advanced driver assistance systems
Multi-sensor object tracking is an important feature for advanced driver assistance systems in future automobiles. Most state-of-the-art systems cannot guarantee deterministic processing of the sensor values due to unsynchronized sensing and processing units. To overcome this shortcoming we propose a paradigm shift towards a time-triggered system architecture providing a deterministic bus syste...
متن کاملTowards a Multilevel Secure Database Management System for Real-Time Applications
Database systems for real-time applications must satisfy timing constraints associated with transactions, in addition to maintaining data consistency. In addition to real-time requirements, security is usually required in many applications, because sensitive information must be safeguarded. Multilevel security requirements introduce a new dimension to transaction processing in real-time databas...
