Cyclic Codes from APN and Planar Functions
نویسنده
چکیده
Cyclic codes are a subclass of linear codes and have applications in consumer electronics, data storage systems, and communication systems as they have efficient encoding and decoding algorithms. In this paper, almost perfect nonlinear functions and planar functions over finite fields are employed to construct a number of classes of cyclic codes. Lower bounds on the minimum weight of some classes of the cyclic codes are developed. The minimum weights of some other classes of the codes constructed in this paper are determined. The dimensions of the codes are flexible. Many of the codes presented in this paper are optimal or almost optimal in the sense that they meet some bound on linear codes. Ten open problems regarding cyclic codes from highly nonlinear functions are also presented.

Quadratic zero-difference balanced functions, APN functions and strongly regular graphs
Let F be a function from Fpn to itself and δ a positive integer. F is called zerodifference δ-balanced if the equation F (x+a)−F (x) = 0 has exactly δ solutions for all nonzero a ∈ Fpn . As a particular case, all known quadratic planar functions are zero-difference 1-balanced; and some quadratic APN functions over F2n are zerodifference 2-balanced. In this paper, we study the relationship betwe...
متن کاملProof of a Conjecture on the Sequence of Exceptional Numbers, Classifying Cyclic Codes and APN Functions
We prove a conjecture that classifies exceptional numbers. This conjecture arises in two different ways, from cryptography and from coding theory. An odd integer t ≥ 3 is said to be exceptional if f(x) = xt is APN (Almost Perfect Nonlinear) over F2n for infinitely many values of n. Equivalently, t is exceptional if the binary cyclic code of length 2n − 1 with two zeros ω, ωt has minimum distanc...
متن کاملSchemes, Codes and Quadratic Zero-Difference Balanced Functions
Zero-difference balanced (ZDB) functions were introduced by Ding for the constructions of optimal and perfect systems of sets and of optimal constant composition codes. In order to be used in these two areas of application, ZDB functions have to be defined on cyclic groups. In this paper, we investigate quadratic ZDB functions from the additive group of Fpn to itself of the form G(x t+1), where...
متن کاملA matrix approach for constructing quadratic APN functions
We find a one to one correspondence between quadratic APN functions without linear and constant terms and a special kind of matrices (We call such matrices as QAMs). Based on the nice mathematical structures of the QAMs, we have developed efficient algorithms to construct quadratic APN functions. On F27 , we have found more than 470 classes of new CCZ-inequivalent quadratic APN functions, which...
متن کاملOn the Fourier Spectra of New APN Functions
Almost perfect nonlinear (APN) functions on F2n are functions achieving the lowest possible differential uniformity. All APN functions discovered until now are either power or quadratic ones, except for one sporadic multinomial nonquadratic example on F26 due to Edel and Pott. It is well known that certain binary codes with good properties can be obtained from APN functions, and determining the...
