Webb30 juni 2024 · Given a square u in Z p and a non-square z in Z p, we describe an algorithm to compute a square root of u which requires T + O ( n 3 / 2) operations (i.e., squarings … Webband so we will only be interested in algorithms whose running time is better than this. We will discuss the following algorithms that work in arbitrary groups: The baby-step/giant-step method, due to Shanks, computes the discrete logarithm in a group of order q in time O(p q polylog(q)). The Pohlig-Hellman algorithm can be used when the ...
