Abstract

Cyber-Physical Systems (CPS) and the Internet have undoubtedly simplified 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. Countless 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 sensitive data generated. This paper seeks to propose a symmetric scheme for securing data in a CPS using IoT sensor-based technology, which will be based on Advanced Encryption Standard(AES) and SHA256 encryption/decryption method.
