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.
