Application of modular turbo codes in authentication systems

Abstract

Low-orbit satellite communication systems (LOSCS) should have the property of noise immunity, which is based on informational, structural and energetic secrecy, as well as noise resistance. One of the directions associated with increasing of informational secrecy is based on the use of a satellite identification system. This system is designed to prevent the imposition of someone else's content on the subscriber through the use of an authentication protocol based on zero-knowledge proof. In a number of works it is proposed to use modular codes (MC) for a reduction of the time of identification of the applicant as MC give the possibility for parallelizing the process of calculations in the protocol. It is known that MC can increase the fault tolerance of the identification system as they are able to eliminate the consequences of failures during operation. But they can also be used to increase the noise immunity of the LOSCS. Thus, the use of a single algebraic system in the construction of MC that are capable of correcting errors caused not only by failures during operation of the identification system, but also by interference in the communication channel, will allow us to abandon cascade codes. Therefore, the development of a method for constructing a modular turbo code for a noise-proof satellite authentication system is an urgent task.
