Modern cryptosystems have a narrow application area, mainly because of a strict restriction of overrunning during the encryption of so-called unicity distance for the key. It is possible to essentially increase the unicity distance by using a synthesis of a constructed/artificial/planned language in the application area, where an alphabet of a high dimension is used. There was made a synthesis of highly secured cryptosystem. It has such feature as the security of text information with an increased unicity distance. This distance is set into a tabular form which assumes that this text information is taken from the thesaurus of predefined application area. There were gotten mathematical expressions that display the procedure of the encryption and decryption. There were considered the features of construction of the generator of pseudorandom sequences. Also, there was defined the level of security of cryptosystem with a different levels of resource capabilities. There was given a graph of correlation between the indicator of security and the code length of the encryption key. There were also defined the conditions of providing a necessary security regime in cloud systems.
