Due to the active development of information technology, information is of great value to date. Any sphere of public life can be described by information, loss or modernization of which can lead to large losses. Thus, information becomes strategic resource of the state and business of all levels that are interested in its preservation. In addition to the natural risks of information loss (failure of technology, natural disasters, etc.), there is also the desire of criminal structures to illegally kidnap or update information. The problem of protecting information is extremely urgent nowadays. Companies require often applications with the most enhanced protection for sending messages. In this article, we implement a scheme for sending encrypted messages between several parties.On the basis of neural networks, we implement symmetric encryption with the distribution of keys. A scheme for synchronizing neural networks using a tree of a parity machine will be constructed.
