Methods and tools for secure sensor data transmission and data mining in energy SCADA system

Abstract

This paper discusses tools for secure sensor data collection, transmission and data mining received from heat metering devices in urban heat supply SCADA system. The effectiveness of supervisory control and data acquisition systems (SCADA) for energy data mining depends on the applied protection technologies of transport environment components. The connection between the heating stations and the dispatch center is established to ensure secure data transmission using virtual private wireless sensor networks (WSN) and secure channels cellular network. The article considers the problems and objectives of key management for data encryption in wireless sensor networks (WSN) of SCADA systems. Three algorithms of hybrid key management using routing information frames determined by routing methods and the WSN topology are presented. Data mining from the hypercube tools are developed on Java Enterprise Edition platform using Spring and ORM Hibernate technologies. JBoss Application server is used as a server platform in the SCADA system.
