Secure data exchange in IIoT
| Resumo: | Industrial Internet of Things (IIoT) plays a central role for the Fourth Industrial Revolution. In the scope of Industry 4.0 many specialists of the field are working together towards implementing large scalable, reliable and secure Industrial environments. However, existing environments are lacking security standards and have limited resources per component which results in various security britches such as trust in between the components, partner factories or remote control units with the system. Due to the resilience and it’s security properties, combining blochchain-based solutions with IIoT environments is gaining popularity. Despite that, chain-structured classic blockchain solutions are extremely resource-intensive and are not suitable for power-constrained IoT devices. To mitigate the security challenges presented above a secure architecture is proposed by using a DAG-structured asynchronous blockchain which can provide system security and transactions efficiency at the same time. Use-cases and sequence diagrams were created to model the solution and a security threat analysis of the architecture is made. Threat analysis is performed based on STRIDE methodology and provides us in depth understanding how our security architecture mitigates the threats and reveals also open challenges. The results are robust, supported by extensive security evaluation, which foster future development over the proposed architecture. Therefore, the contributions made are valid, and as the architecture is generic, will be possible to deploy it in diverse custom industrial environments. The flexibility of the architecture will allow incorporation of future hardware and software development in the field. |
