ESTADO — Enabling smart services for industrial equipment through a secured, transparent and ad-hoc data transmission online

Abstract

The advent of initiatives like Industry 4.0 promises increased operational efficiency through smart services and interconnected devices. To enable smart maintenance services for today's and future industrial equipment, regular status information must be transmitted from device customers to maintenance service providers over the Internet. However, simply attaching an industrial device to the Internet often leads to a security and privacy nightmare. Transparency about when and what data is being transmitted is of crucial interest to a customer. During transport, data must be protected against modifications and disclosure. A maintainer requires trust in the data's origin and integrity.In this paper, we propose ESTADO, a system that enables smart services by providing the necessary connectivity from industrial equipment to service providers for device state tracking. Our system design focuses on the migration of current devices and the security aspect. Using a non-permanent NFC based connection, connectivity is only established ad-hoc on customer demand, and any data transmission is fully transparent to a customer. We study our design through a prototype implementation using an Infineon security controller and evaluate the security, usability and deployment aspects of our solution.

A Systematic Survey of Industrial Internet of Things Security: Requirements and Fog Computing Opportunities

“…Lesjak et al [36] reason that smart maintenance requires secure communication channels, as status information of machines is sensitive data. Moreover, the maintainer needs the ability to verify the validity of this data.…”

“…In today's world, data security is critical in nearly any digital environment, and the IIoT is no different. Many of the works investigated in this survey identify confidentiality of data as a security requirement in some form (e.g., [17], [36], [49], [71], [133], [136]). Traditionally however, availability and integrity are considered more favorable than confidentiality for industrial environments [129], [132], as they have a measurable economic impact.…”

Internet of Things Security Requirements, Threats, Attacks, and Countermeasures

“…Henceforward, the digital world record maintaining the security of data as an important security aspect, and the introduction of IoT make the data security indispensable aspect of the design of secure IoT systems. Several studies considered the data confidentiality as security necessity for IoT data [14][15][16][17][18]. Conventionally nevertheless, data integrity and data availability are deemed more advantageous than confidentiality especially in industrial ecosystems [19,20], thanks to the fact that they have a quantifiable commercial effect.…”
