  • Abstract
    A simple method showing the quadratic character in a finite field of odd order q can be computed in O(log2 q) steps is presented. It is also shown how sequences generated deterministically from a random seed can be used reliably in a recent randomized algorithm of R. Peralta (1986) for computing square roots in finite fields
