Traffic and criteria management in software-defined networks (SDN) is performed by a controller in conjunction with a switch that operates using the OpenFlow protocol. The OpenFlow protocol is the main part of SDN. Thus, the OpenFlow protocol successfully allows you to cope with the increased requirements for user traffic, priority. The relevance of the research is that there are 9 types of attacks on SDN, most of them are security-related and solved by encryption, the rest are traffic problems. The aim of the research is to transfer traffic in SDN using authentication and bitwise encryption on controller side to reduce man-inthe-middle attacks. The algorithm uses bitwise symmetric encryption with a key obtained by Diffie-Hellman algorithm. To research the algorithm, a simulation model was developed, including the use of the algorithm on the apparatus of Petri nets. Simulation results showed that the proposed traffic transfer in SDN using authentication and bitwise encryption on controller side made it possible to ensure secure transmission for man-in-the-middle attacks, calculate keys without allowing transmission over the network in open form, and also increase the speed of traffic encryption in SDN
