As the Internet expands both in number of hosts connected and in terms of the number of services provided, security has become a key issue for the technology developers. This work presents and analyses a prototype of an intrusion detection system. This system, positioned at key points of the network, will keep looking at the passing packets, in search of(More)
Latest Fusion energy experiments envision a quasi-continuous operation regime. In consequence, the largest experimental devices, currently in development, specify high-availability (HA) requirements for the whole plant infrastructure. HA features enable the whole facility to perform seamlessly in the case of failure of any of its components, coping with the(More)
The Instituto de Plasmas e Fusão Nuclear (IPFN) has developed dedicated reconfigurable modules based on field programmable gate array (FPGA) devices for several nuclear fusion machines worldwide. Moreover, new Advanced Telecommunication Computing Architecture (ATCA) based modules developed by IPFN are already included in the ITER fast plant(More)
