Therefore, it is necessary to improve constantly existing and develop new algorithms that will ensure accurate and secure data transfer. This leads to the intensive development of coding theory and cryptography as scientific fields which solve these problems. To ensure efficient and secure data transmission at the same time, the concept of cryptcoding is developed such that the coding and encryption processes are merged into one process. Cryptcodes provide correction of a certain number of errors in the transmitted message and data confidentiality, using only one algorithm. The main research in this field is to define new algorithms for coding that detects and corrects errors, random codes, stream ciphers, block ciphers, pseudo-random generators, hash functions, etc. This monograph examines an application of quasigroups for designing error-correcting cryptcodes, called Random Codes Based on Quasigroups (RCBQ ). These codes are a combination of cryptographic algorithms and error-correcting codes and depend on several parameters. Some modifications (new coding/decoding algorithms) of RCBQ for improving their performances for transmission ordinary messages, images, and audio files trough a binary-symmetric channel, Gaussian channel, and burst channels are considered. Also, authors propose and analyze filter for visually enhance of the decoded images and improving the quality of decoded audio files.SpringerBriefs in Information Security and Cryptography,2731-9563Data protectionCoding theoryInformation theoryComputer networksCryptographyData encryption (Computer science)Set theoryAlgebraData and Information SecurityCoding and Information TheoryComputer Communication NetworksCryptologySet TheoryOrder, Lattices, Ordered Algebraic StructuresData protection.Coding theory.Information theory.Computer networks.Cryptography.Data encryption (Computer science)Set theory.Algebra.Data and Information Security.Coding and Information Theory.Computer Communication Networks.Cryptology.Set Theory.Order, Lattices, Ordered Algebraic Structures.003.54Mechkaroska Daniela1587105Popovska-Mitrovikj AleksandraBakeva VericaMiAaPQMiAaPQMiAaPQBOOK9910800117103321Cryptocoding Based on Quasigroups3874452UNINA
