WebbLast week, we saw Tonelli-Shanks algorithm to compute square roots modulo an odd prime pin O(log3 p). The first step of this exercise is to design an algorithm to compute square roots modulo pv, for some v 2 and odd prime p. 1.Let x2(Z=pvZ) . Show that x2 1 [pv] if and only if x 1 [pv]. Let ’be the Euler totient function. The Tonelli–Shanks algorithm can (naturally) be used for any process in which square roots modulo a prime are necessary. For example, it can be used for finding points on elliptic curves. It is also useful for the computations in the Rabin cryptosystem and in the sieving step of the quadratic sieve.
