Abstract:

Complete permutation polynomials (CPPs) over finite fields have important applications in cryptography,coding theory,and combinatorial design theory.The block cipher algorithm SMS4 published in China in 2006 is designed based on CPPs.Recently,CPPs have been used in the constructions of cryptographic functions.Thus,the construction of CPPs over finite fields has become a hot research topic in cryptography.CPPs with few terms,especially monomial CPPs over finite fields,attract people's attention due to their simple algebraic form and easy realization.In this paper,a detailed survey of the constructions of monomial CPPs is presented.Then we give a class of monomial CPPs over finite fields with an odd characteristic by using a powerful criterion for permutation polynomials.Our construction enriches the results of monomial CPPs.In addition,we also calculate the inverses of these bijective monomials.

Key words: finite fields, monomial complete permutation polynomials, odd characteristic
