Our society greatly depends on services and applications provided by mobile communication networks. As billions of people and devices become connected, it becomes increasingly important to guarantee security of interactions of all players. In this talk we address several aspects of this important, many-folded problem. First, we show how to design cryptographic primitives which can assure integrity and confidentiality of transmitted messages while satisfying resource constrains of low-end low-cost wireless devices such as sensors or RFID tags. Second, we describe countermeasures which can enhance the resistance of hardware implementing cryptographic algorithms to hardware Trojans.

In recent years, museums are exploring digital and computer technologies to enhance visitor experience and for that purpose a variety of systems for creating 3D sound effects for museums have been implemented. The growth of the performance of low-cost minicomputers leads to the issue of their integration with home theatre systems for simple implementation of 3D sound effects. This paper presents one solution for implementing 3D sound effects for auditory illusions immersive experiences in museums using the Raspberry Pi minicomputer and a home theatre system with 5.1 surround sound. With this solution it is possible to create a museum visitor detector via Raspberry Pi that uses motion detection to trigger 3D sound playing on a home theatre system. The solution was experimentally tested developing an audio system called “Auditory Illusions for Concentration Camp Museums”. The system was developed to enrich the exhibition in the Red Cross Second World War Concentration Camp Museum in the city of Niš, Serbia.
