This paper presents a design-space exploration of an applicationspecific instruction-set processor (ASIP) for the computation of various cryptographic pairings over Barreto-Naehrig curves (BN curves). Cryptographic pairings are based on elliptic curves over finite fields—in the case of BN curves a field Fp of large prime order p. Efficient arithmetic in(More)

We present a one-dimensional model to analyze routing strategy N F P (Nearest with Forward Progress) for a multihop packet radio network. It is assumed that each station has adjustable transmission range to address target nodes, distributed on a line according to a nonhomogeneous Poisson process. N F P transmits to the nearest neighbor in the desired(More)
