Several new classes of p-ary weakly regular plateaued functions and minimal codes with several weights
Plateaued functions, including bent functions, are crucial in cryptography due to their possession of a range of desirable cryptographic properties. Weakly regular plateaued functions can also be employed in many domains. In particular, they have been widely used in designing good linear codes for several applications (such as secret sharing and two-party computation), association schemes, and strongly regular graphs. This paper is devoted to weakly regular plateaued functions, whose objectives are twofold. First, we aim to generate new infinite families of weakly regular plateaued functions and then, to design new families of p-ary linear codes and investigate their use for some standard applications after studying its minimality based on their weight distributions. More specifically, we present several classes of weakly regular plateaued functions from monomial bent functions, and determine their corresponding dual functions explicitly. Furthermore, we exploit our constructions to derive several new classes of minimal linear codes violating the Ashikhmin-Barg condition with six, seven, nine, ten or eleven weights, which are more appropriate for several applications.
期刊介绍:
Finite Fields and Their Applications is a peer-reviewed technical journal publishing papers in finite field theory as well as in applications of finite fields. As a result of applications in a wide variety of areas, finite fields are increasingly important in several areas of mathematics, including linear and abstract algebra, number theory and algebraic geometry, as well as in computer science, statistics, information theory, and engineering.
For cohesion, and because so many applications rely on various theoretical properties of finite fields, it is essential that there be a core of high-quality papers on theoretical aspects. In addition, since much of the vitality of the area comes from computational problems, the journal publishes papers on computational aspects of finite fields as well as on algorithms and complexity of finite field-related methods.
The journal also publishes papers in various applications including, but not limited to, algebraic coding theory, cryptology, combinatorial design theory, pseudorandom number generation, and linear recurring sequences. There are other areas of application to be included, but the important point is that finite fields play a nontrivial role in the theory, application, or algorithm.
