DATA SECURITY, MODELING AND VISUALIZATION OF DATA FROM IOT DEVICES

The article describes the IoT infrastructure, hardware of system, considers issue security chosen LoRa data transmission technology. Data was received from sensors for gas, temperature and humidity, atmospheric pressure, as well location end device. At same time, standardized features selected technology transmitting to server were investigated. deals with bi-directional secure communication line, function requires devices/end devices be configured through gateway. Security research is devoted development a mechanism increase its resilience. payload formed hash last bytes, entire encrypted AES integrity confidentiality. A method assessing visualizing air pollution given on example city Almaty, Kazakhstan. process numerical modeling study emissions harmful substances into atmosphere based mathematical model by system Navier-Stokes equations, consisting continuity equation, equations motion k-epsilon turbulence model. To test methods processing mixing chemical reactions, problem – jet in transverse flow. Three-dimensional simulation has been implemented. use Internet Things (IoT) acquisition big made it possible simultaneously observe concentrations several pollutants atmosphere, calculate this concentration analyze state surface layer. Modeling allows forecasting certain areas at times year.
