The subject is the information communication in IT- systems. The goal is the information protection. The method used is the cryptography with secret key. The information is transferred between the devices in IT-system. The open communication channels are used. The information protection used the symmetric method of block enciphering. The cryptographic information security method used the block ciphering with the secret key. The secret key is appended by the random information. The number of digits in the secret key increased to the information block size. The cryptographic hack becomes impossible.
