— We present in this paper a new security protocol especially suited for sensor networks. This protocol uses a novel encryption method for secure message transmission. We present the details of this encryption scheme along with experimental results performed on a network simulator.
In this paper we show that the already known method of using multiplexers for making the inputs and outputs of the embedded blocks accessible by the primary ports of the Integrated Circuit (IC) can be used for path delay fault testing of the IC. We show that the testing of the IC for path delay faults can be reduced to the testing of each block.… (More)
— High reliability requirements in many modern applications make soft errors an extremely important design aspect and pose new challenges in nanometer technologies. In addition, timing faults that may escape fabrication tests become a real concern in high complexity, high frequency designs. To confront this situation, a concurrent error detection and… (More)
We propose a new concurrent soft and timing error detection circuit that exploits the time redundancy approach to achieve tolerance with respect to transient and delay faults. The idea is based on current mode sense amplifier topologies to provide fast error detection times.
