摘要：The study discusses the MQTT (Message Queuing Telemetry Transport) protocol for the Internet of Things and sensor wireless networks, its features, application options, and specific procedures. The information elements and principles of the message owner are analysed. The identification of users proposed in this study is carried out by identifying them from the Cloudant database. Such application runs on the Node.js server (JavaScript) in the IBM (International Business Machines) Bluemix environment and provides a RESTful API (Representational State Transfer Application Programming Interface) or which requires mobile client access to authenticate users. The mobile client access service is designed to activate these two APIs in any authentication application. The scientific novelty is determined by the fact that it is proposed to use separate approaches to authentication for a web application � on Cloud Directory, and for a mobile application � MobileFirst Client Access. However, both web and mobile applications use the same level of application security to allow the user to access device data. The practical significance of the study is determined by the fact that the transport layer security protocol increases the performance of the protocol and reduces computational costs, but it is not used when the initial connection to the server or in cases where the previous session has already expired. The study presents an algorithm for detecting weak symmetry breaking for analysing the randomness of a reconstructed electronic message. The study proposes a method of homomorphic encryption and authentication of users and their electronic messages in wireless sensor networks of the Internet of Things.
