— This paper presents a simulation tool that can be used for the evaluation of real-time behavior for a wide range of parallel and distributed systems. The simulator is based on a flexible workload and CPU/execution model that covers different multiprocessor scenarios, from parallel systems and independent task sets to distributed environments and task(More)
There are several programming paradigms that help programmers write efficient and verifiable code for distributed environments. These solutions, however, often lack proper support for local parallelism. In this article we try to improve existing solutions for providing a distributed, highly parallel framework that is easy to program. We propose an extension(More)
The paper presents the architecture of a distributed software system that manages patients' health records and assures remote and interactive access to medical services. In order to cover the complex relationships between different medical concepts (symptoms, diseases, treatment, medication, etc.) and also to include " intelligence " in the software system(More)
—The memory of any digital system stores sensitive information that needs to be protected from any type of attacks. In the last decade, device specific attacks have been reported and analyzed, attacks that successfully extract private encryption keys from AES algorithms. In this work, a novel technique is proposed which targets the increase of security in(More)
Clustering is an important problem in malware research, as the number of malicious samples that appear every day makes manual analysis impractical. Although these samples belong to a limited number of malware families, it is difficult to categorize them automatically as obfuscation is involved. By extracting relevant features we can apply clustering(More)
