Secure Communication between Information Technology and Operational Technology
IECON 2021 - 47TH ANNUAL CONFERENCE OF THE IEEE INDUSTRIAL ELECTRONICS SOCIETY(2021)
Abstract
Interconnectedness is an important feature of components in future industrial domains. Internet of Things, Industry 4.0, Cyber Physical Systems, autonomous driving, etc. are some new paradigms that require interconnectedness as an important basis. The interconnectedness plays a crucial role to fulfill the future requirements but at the same time can cause unauthorized access to the systems and increases the probability of system attacks. Future systems consist of large number of components that communicate with each other. These components have different requirements (i.e. availability, real-time, security). Especially, the communication and information exchange with high critical components must be controlled. This paper addresses a secure and unidirectional communication between high critical components and components with lower level of criticality on the same hardware.
