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. 0aData protection. 0aCoding theory.965513 0aInformation theory.957783 0aComputer networks .960157 0aCryptography.964299 0aData encryption (Computer science).958243 0aSet theory. 0aAlgebra.9150114aData and Information Security.96649224aCoding and Information Theory.96551524aComputer Communication Networks.96568924aCryptology.96649124aSet Theory.24aOrder, Lattices, Ordered Algebraic Structures.9695001 aPopovska-Mitrovikj, Aleksandra.eauthor.4aut4http://id.loc.gov/vocabulary/relators/aut9695011 aBakeva, Verica.eauthor.4aut4http://id.loc.gov/vocabulary/relators/aut9695022 aSpringerLink (Online service)0 tSpringer Nature eBook08iPrinted edition:z978303150124108iPrinted edition:z9783031501265 0aSpringerBriefs in Information Security and Cryptography,x2731-956396950340uhttps://doi.org/10.1007/978-3-031-50125-8  aZDB-2-SCS  aZDB-2-SXCS  c57176d57176
