Multi-core computing platforms have recently been introduced in the vehicle domain to enable novel data-intensive and computation-demanding features in advanced real-time embedded system applications (e.g., a modern car) that could not be supported by traditional single-core computing platforms. Although the existing model- and component-basedsoftware development techniques can efficiently deal with the challenge of managing the software complexity in these systems, the core challenge of ensuring their timing predictability comes at the cost of performance loss and underutilization of the systems' resources. This paper identifies a sheer standoff between ensuring timing predictability and performance when the traditional model- and component-basedsoftware development techniques are used to develop software architectures of these systems. Note that ensuring timing predictability of a real-time system during its development is as important as ensuring its correct logical functionality. This paper takes the position that the traditional techniques fail to resolve this standoff mainly because they consider the following three viewpoints either in isolation or in pairs, but not altogether: (i) viewpoint of the software architecture modeling, (ii) viewpoint of the execution environment modeling, and (iii) viewpoint of the timing predictability verification. To mitigate this standoff, the paper discusses several approaches and points out opportunities for further research in developing a novel model- and component-basedsoftware development framework that jointly considers the three viewpoints during the development of these systems.

Scenario modeling for Autonomous Driving Systems (ADS) enables scenario-based simulation and verification which are critical for the development of safe ADS. However, with the increasing complexity and uncertainty of ADS, it becomes increasingly challenging to manually model driving scenarios and conduct verification analysis. To tackle these challenges, we propose a novel and pragmatic framework for scenario modeling, simulation and verification. The novelty is that it's a verification-in-the-loop scenario modeling framework. The scenario modeling language with formal semantics is proposed based on the domain knowledge of ADS. It facilitates scenario verification to analyze the safety of scenario models. Moreover, the scenario simulation is implemented based on the scenario executor. Compared with existing works, our framework can simplify the description of scenarios in a non-programming, user-friendly manner, model stochastic behavior of vehicles, support safe verification of scenario models with UPPAAL-SMC and generate executable scenario in some open-source simulators such as CARLA. To preliminarily demonstrate the effectiveness and feasibility of our approach, we build a prototype tool and apply our approach in several typical scenarios for ADS.

In the face of increased threats within software registries and management systems, we address the critical need for effective malicious code detection. In this paper, we propose an innovative approach that integrates source code slicing, inter-procedural analysis, and cross-file inter-procedural analysis, thereby enhancing the detection precision and reducing false positives. This approach has been encapsulated within a multi-analysis-based framework for automatic detection of malicious code in real-world software packages. In its application to major third-party software registries like PyPI and NPM, our framework has proven effective, identifying 130 malicious packages from a total of 169,640 monitored over a continuous period of five weeks. This work advances the current state-of-the-art solution to malicious code detection, demonstrating significant practical impact in strengthening the software supply chain defense.
