Radio Frequency Identification (RFID) security has not been properly handled in numerous applications, such as in public transportation systems. In this paper, a methodology to reverse engineer and detect security flaws is put into practice. Specifically, the communications protocol of an ISO/IEC 14443-B public transportation card used by hundreds of thousands of people in Spain was analyzed. By applying...
Recent researches have studied how to support the online distribution of multimedia contents efficiently, reducing almost completely the state information within switching nodes. However, many of these studies have been carried out only in a theoretical way and have been verified by simulations, without actual hardware implementations, which will reveal their true performance. One of the main proposals...
Power consumption has become the biggest challenge in industry for chip design. We will present that by using small reprogrammable embedded FPGAs (eFPGA) coupled with a processor we can achieve power and energy reduction with a very small silicon overhead. Enhancement of computational power helps lowering down frequency (dynamic frequency scaling) to decrease dynamic power. By having same computational...
Dynamically reconfigurable architectures are emerging as a viable design alternative to implement a wide range of computationally intensive applications. At the same time, an urgent necessity has arisen for support tool development to automate the design process and achieve optimal exploitation of the architectural features of the system. Task scheduling and context (configuration) management become...
