Crypto-Steganographic System based on the Solver of the Square Root of a Prime Number

Due to the fact that steganographic and cryptographic data transformations are used effectively for ensuring the confidentiality, integrity and authenticity of information, the development of methods to improve the reliability and authenticity of crypto-steganographic systems is a promising area. This paper proposes several approaches to using a pseudorandom number generator in steganography and cryptography based on the solver of the square root of a prime number. The proposed algorithms are used to hide encrypted information in a WAV audio file. The application of the developed algorithms does not change the quality of human perception of sound but makes it difficult to detect the fact of information hiding.
