Remarks on Self-Inverse
Quadratic Permutation Polynomials, Horacio Tapia-Recillas · 2010
Conditions for a quadratic permutation polynomial (QPP) to be self-inverse over the ring Zm of modular integers are given. If m = 2 n , necessary and sufficient conditions for a QPP to be self-inverse are determined. Additional properties of QPP over modular integers as well as examples of monomial permutation polynomials are also provided.
