WebbIf we have a non quadratic residue in Fq we can apply Tonelli Shanks algorithm to compute the square root. Using Skalba equality the authors of [16] show that a modifica- tion of Tonelli-Shanks algorithm can compute square roots deterministicaly in time O(log4 q). Shallue-Woestijne method runs in time O(log4 q) for any field size q = pn and ... Webb13 juni 2024 · computationally, giving the order of 19 as the odd number 29, which allows to compute a square root from 19 2 ⋅ 15 = 19 ( mod 59). This gives one (the?) pair of square roots as x = ± 19 15 = ± 14 ( mod 59).

Webb1 jan. 2002 · The algorithm of Tonelli and Shanks for computing square roots modulo a prime number is the most used, and probably the fastest among the known algorithms when averaged over all prime numbers. However, for some particular prime numbers, there are other algorithms which are considerably faster.

"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. Visa mer The Tonelli–Shanks algorithm (referred to by Shanks as the RESSOL algorithm) is used in modular arithmetic to solve for r in a congruence of the form r ≡ n (mod p), where p is a prime: that is, to find a square root of n modulo p. Visa mer Tonelli–Shanks can be generalized to any cyclic group (instead of $${\displaystyle (\mathbb {Z} /p\mathbb {Z} )^{\times }}$$) and to kth roots for … Visa mer Given a non-zero $${\displaystyle n}$$ and an odd prime $${\displaystyle p}$$, Euler's criterion tells us that $${\displaystyle n}$$ has a square root (i.e., $${\displaystyle n}$$ Visa mer The Tonelli–Shanks algorithm requires (on average over all possible input (quadratic residues and quadratic nonresidues)) modular … Visa mer " - Shanks tonelli algorithm
