Abstract
Self-orthogonal codes have interesting applications in quantum codes, linear complementary dual (LCD) codes and lattices. LCD codes and (almost) optimally extendable codes are useful to safeguard against Side-Channel Attacks (SCAs) and Fault Injection Attacks (FIAs). In this paper, we first give a lower bound of dual distances for augmented codes via the defining-set construction. Then we construct two families of q-ary self-orthogonal codes with determined weight distributions via defining-set construction and propose the parameters of their duals. Besides, several families of AMDS codes are obtained as byproducts, which are both length-optimal and dimension-optimal with respect to the Sphere-packing bound. As applications, these self-orthogonal codes are used to construct LCD codes and proved to be optimally extendable. As a consequence, our constructions produce some optimal codes.
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.
