Modified Asymmetric and Hash Algorithms for InternetEnabled Industrial Automation
Industrial automation systems are specially designed for monitoring, controlling and smooth plant operations. Automation systems use the internet for monitoring and control of process parameters. The security threats increases due to the internet is an open environment. Automation devices are not built with security mechanisms preferably for the internet enables process equipment. This proposed work is the implementation ofsecure monitoring of plant information through the Supervisory Control and Data Acquisition (SCADA) system. This modified asymmetric and hash algorithm is proposed which generates the large key size of 2048-bit and 512-bit respectively. This proposed algorithm is implemented using the ARM Cortex A53 processor which performs data encryption and decryption. The ARM Cortex processor used in this proposed work is low-cost, 1.2 GHz quad-core, 1 GB RAM, 802.11n wireless standard, inbuilt High Definition Multi-media Interface, Ethernet and four USB ports. It offers low latency in generating the encrypted process data. This encrypted unreadable information is transmitted across the internet. The process data is decrypted using embedded system at the receiver and the original process data is received through the SCADA system. It provides authentication and integrity of process information across the internet. It achieves a data transfer rate of 300 Megabits per second and more than 95 percent efficiency. This proposed work can be applied for securing the internet-enabled industrial automation process and allows secure monitoring of plant information in remote areas.
