A Java Framework for Spatial Embedded Systems

Satellite constellations will soon play a fundamental role in global broadband and heterogeneous communication architectures. These constellations will offer ubiquitous access to interactive multimedia services. Spatial embedded systems must evolve accordingly to provide a robust real time support, including a dynamically extensible runtime environment. In other words, these systems must allow new services or features to be dynamically loaded and linked to the embedded software. Object technology answers the need for dynamically extensible systems. But can it also answer the constraints of embedded real-time systems? First experiments with Java indicate that an efficient real time scheduling of Java tasks can be implemented on top of a real-time kernel. The paper also brings solutions for an efficient and robust memory management Thus, the paper shows that it is realistic, proficient and cost effective to use object technology for designing the new generation of real-time embedded systems

Car2X communication: Securing the last meter: A cost-effective approach for ensuring trust in Car2X applications using in-vehicle symmetric cryptography

The effectiveness of Car2X communication strongly relies on trust in received data. Securing in-vehicle communication is an essential yet so far overlooked step to achieve this objective. We present an approach based on the use of symmetric key material protected with inexpensive hardware. We modeled the involved cryptographic and network protocols, showed their applicability to automotive bus systems and conclude about their soundness with analytical and simulation methods. A prototype realization in real vehicles is envisaged as part of an ongoing project

Security requirements for automotive on-board networks

This paper considers security requirements for automotive on-board networks and describes the processes used for identifying and prioritizing such requirements. The security engineering process starts from use cases for automotive on-board networks that require wireless communication interfaces and involves an investigation of security threat scenarios and the assessment of the relative risks associated with the threats
