In this paper we present a software system for cryptographic information protection based on deterministic chaos. The program system functionality includes encryption and decryption of text and graphic information on the basis of a random number generator, which is played by the Lorentz attractor. The use of an attractor in this program system guarantees randomness and absolute randomness when issuing numbers, limited only by the initial parameters. It is also necessary to transfer encryption parameters, excluding the possibility of its interception, because Encryption parameters are used in the program as decryption keys. After the process of text encryption, the program performs a frequency analysis of the input and output files. Accordingly, the frequency of a certain group of letters, which is vulnerable to frequency analysis, must be clearly expressed in the input file. In the output file, the frequency should be stable and uniform, thereby proving the effectiveness of encryption.
