| Abstract: | This article examines the improvement of homophonic encryption using the well-known Z408 cipher as an example, and analyzes their problems to further correct the main shortcomings of this typea of encryption. In the practical part, an encryption system similar to Z408 was created and the complexity ofthe language analysis for this cipher was increased. The correlation dat of the number of alternative characters was used to improve the transmission of encrypted data depending on the load of the device. The more symbols and the higher the load, the fewer the number of alternative symbols will be used. |
