Cybersecurity is a major concern for Industry 4.0, especially for embedded devices. OPC UA PubSub provides the appropriate mechanisms to build a scalable, secure and interoperable solution with end-to-end encryption.
This article, published by Elsevier, is the result of a joint collaboration with Thales R&T to build an innovative solution. It is based on open source software (S2OPC and TPM library) and COTS hardware (in particular STM4RasPI extension board from STMicroelectronics).
