Fibonacci self-reciprocal polynomials and Fibonacci permutation polynomials
Let p be a prime. In this paper, we give a complete classification of self-reciprocal polynomials arising from Fibonacci polynomials over Z and Zp, where p=2 and p>5

. We also present some partial results when
p=3,5
. We also compute the first and second moments of Fibonacci polynomials

over finite fields, which give necessary conditions for Fibonacci polynomials to be permutation polynomials over finite fields.
