In this article is being reviewed different approaches to optimize data exchange in a network using cryptography - to make any date secure, compression - to make any data smaller and accelerated routing, which is based on meta information about target destination: how far they are, how loaded they are. The object of research is the process of data exchange in the network. The purpose of the study is to optimize the process of data exchange in the network in order to improve the security and

... d of data transfer. Research methods - statistical analysis of data transmission efficiency indicators. When transmitting data, cryptographic algorithms are used to ensure integrity and security, these algorithms allow the exchange of data using public and private key technology. But now this may not be enough to complicate the process of decrypting the data, it is advisable to make the messages transmitted between nodes as similar as possible to each other, for example, the same length. This solution will minimize the possibility of revealing the cipher by analysis for the attacker, but at the same time significantly increases the volume of transmitted messages due to the additional «masking» amount of data. To compensate for this effect in high-load networks, it is proposed to use a smart routing algorithm, which allows you to choose the optimal route for messages, taking into account the load of routers and channels between them.
