METHOD OF ENCRYPTION/DECRYPTION OF DATA ON THE BASIS OF THE PIXEL ALPHABET OF MONOCHROME IMAGE

Improving the availability of information technology and increasing volume digital traffic leads to an important problem data protection. A particularly pressing issue is transmitting confidential through unsecured communication channels, such as Internet. Recently, there has been a significant increase in number cyberattacks, including attempts intercept steal transmitted global networks. Information security computer telecommunication systems priority. To date, one most reliable methods protecting rightly considered be encryption. Cryptographic transformations are effective way for system maintain confidentiality it entered, output, transmitted, processed, stored, resist its destruction, theft, or distortion. But ensure combined use steganographic cryptographic means. In order high stability encrypted when network telecommunications reduce threat unauthorized access attack on cipher, proposed change approach solving method encrypting / decrypting text based pixel alphabet monochrome image, which hiding distorting graphic data, proposed. This allows you significantly risk cipher by each character with dynamic random from range values corresponding position data. sender recipient only.
