In this paper the benefits of implementation of the Tate pair-ing computation in dedicated hardware are discussed. The main observation lies in the fact that arithmetic architectures in the extension field GF (3 6m) are good candidates for parallelization, leading to a similar calculation time in hardware as for operations over the base field GF (3 m).(More)
This paper presents an energy-efficient medium access control protocol suitable for communication in a wireless body area network for remote monitoring of physiological signals such as EEG and ECG. The protocol takes advantage of the static nature of the body area network to implement the effective time-division multiple access (TDMA) strategy with very(More)
There has been a lot of interest in recent years in the problems faced by cryptosystems due to side channel attacks. Algorithms for elliptic curve point scalar multiplication such as the double-and-add method are prone to such attacks. By making use of special addition chains, it is possible to implement a Simple Power Analysis (SPA) resistant cryptosystem.(More)
—We designed, implemented, tested and measured an ultra low power Wake Up Receiver (WUR), intended for use in Wireless Body Area Networks (WBAN). Gaussian On-Off Keying (GOOK) and Pulse Width Modulation (PWM) are used to modulate and encode, respectively, the preamble signal. The receiver incorporates a decoder to enable Serial Peripheral Interface (SPI).(More)
