The fourth and sixth power mean of the classical Kloosterman sums

The main purpose of this paper is using the elementary and algebraic methods to study the computational problems of the fourth and sixth power mean of the classical Kloosterman sums, and to give an exact computation formula and conversion formula for them.     

A class of binary cyclic codes with generalized Niho exponents

In this paper, a class of binary cyclic codes with three generalized Niho-type nonzeros is introduced. Based on some techniques in solving certain equations over finite fields, the proposed cyclic codes are shown to have six nonzero weights and the weight distribution is also completely determined.
