Constructions of complete permutations over $F_{q}^{n}$

Sartaj Ul Hasan, Ramandeep Kaur, Hridesh Kumar +2

Complete permutation polynomials play an important role in cryptography, particularly in the design of cryptographic primitives such as the Lai--Massey scheme and S-boxes. We gener…

Enumeration of certain permutation group polynomials

Sartaj Ul Hasan, Ramandeep Kaur, Hridesh Kumar

We construct a new family of permutation group polynomials over finite fields of odd characteristic and explicitly provide its companion. Moreover, we precisely determine the numbe…

Permutation polynomials from the trace functions

Sartaj Ul Hasan, Ramandeep Kaur, Hridesh Kumar

We study necessary and sufficient conditions on $γ$ for several classes of polynomials of the form $X + γ Tr_{q}^{q^{n}} (h (X))$ to be permutation polynomials over finite…
