Psychoacoustic Model Based Audio Data Compression Technique: An Approach Using DWT and VQ
Main Article Content
Abstract
SwpemsoirJ Control an d Data Acquisition (SCADA) networks are used by m any o f the utility companies that form the critical infrastructure in m any countries to control field devices from a central station. In recent years, SCADA networks have also enjoyed an increase in popularity within process control industries for monitoring an d control. The use o f the Internet can facilitate the remote monitoring o f the SCADA systems but with the sharp increase in actual an d potential threats against SCADA has made it dangerous to use the unsecured communication protocols. This paper presents a secure architecture to access SCADA-controlled devices remotely using the Internet. Using this architecture, SCADA engineers can get the current process information an d send the control data to a remote plan t through their web browser securely. This Internet-based approach has been implemented and tested for remote monitoring and control of a chemical-process test-bed.
