This paper proposes an evaluation and comparison of guidelines and techniques that allow the creation of secure Web services to determine whether the application has the desired characteristics related to performance and security. In this sense it is crucial evaluate the cryptographic algorithms and the key length used. The results obtained allow to(More)
This paper presents the development of two outdoor intelligent vehicles platforms named CaRINA I and CaRINA II, their system architecture, simulation tools, and control modules. It also describes the development of the intelligent control system modules allowing the mobile robots and vehicles to navigate autonomously in controlled urban environments.(More)
This paper presents a new implementation and evaluation of digital signature for mobile devices. This digital signature system takes into account the device limitations and thus generates a functional digital signature. Its efficiency is described and justified along the paper. It also presents a case study that allows the evaluation of the device(More)
—In this paper is shown an evaluation and comparison of techniques that allow the validation of the Web services used, to determine characteristics related to performance and security. In this sense, it is crucial evaluate the cryptography and digital signature performance in SOAP messages, performing the change of cryptographic algorithms, as well as the(More)
Flying Ad hoc Network (FANET) is an infrastructure-less multi-hop radio ad hoc network in which Unmanned Aerial Vehicles (UAVs) and Ground Control Station (GCS) collaborates to forward data traffic. Compared to the standard Mobile Ad hoc NETworks (MANETs), the FANET architecture has some specific features (3D mobility, low UAV density, intermittent network(More)
Unmanned aircraft systems are a specific type of critical embedded system that has been focus of research in recent years. In these systems, when fault of any kind occur, high value assets are placed at risk, and in some cases even human lives. Due to their high criticality, the development of improvements to these systems in order to increase the safety(More)
