A Symmetric Scheme for Securing Data in Cyber-Physical Systems / IoT Sensor-Based Systems based on AES and SHA256

Abstract

Cyber-Physical technologies and Internet have modernized and enhanced the lifestyle of people in this present era. Internet of Things (IoT) is also being seen as the new technology that is changing human discernment about daily life. Many cyber physical devices generate a lot of sensitive data, which needs to be secured. All the applications of CPS / IoT fundamentally, need symmetric keys for the encryption / decryption of the sensitive data generated. This paper seeks to propose a symmetric scheme for securing data in a Cyber-Physical system using IoT sensor-based technology, which will be based on AES and SHA256 encryption / decryption method.
