SQUARE ROOTS IN FINITE FIELDS AND QUADRATIC NONRESIDUES JEREMY BOOHER The law of quadratic reciprocity is a well-known and beautiful result about when a number is a quadratic residue (non-zero square) modulo a prime p. Solving the quadratic congruence x 2 ≡ a (mod m) This works for m with up to say 20 digits, due to the limitations of the program used to factor m. Repeat until it returns a number not equal to the one we originally squared (or its negative modulo n ), then follow the algorithm described in congruence of squares. code modulo n. For an example, note that $$2^2 \equiv -1$$ modulo $$5$$. It is clear that being a quadratic residue, or nonresidue, is a characteristic of the entire residue class of a modulo n. Generate a random number, square it modulo n, and have the efficient square root algorithm find a root. If the modulus m is a prime integer, then all coefficient arithmetic is done in the finite field of integers modulo m. ) (b) Find a square root of 253 modulo 3143.
