Abstract
Systems and methods for security of industrial data streams are provided herein. Methods according to various embodiments include provisioning a fogNode that is communicatively coupled with a fog cloud manager through a forwarder of the fogNode and providing a fogLet within the fogNode, the fogLet communicating with a plurality of operational technology devices. Embodiments include providing fogLet identification information using hardware root of trust of the fogNode, the hardware root of trust of the fogNode being a Trusted Platform Module (TPM) of the fogNode. Embodiments further comprise communicating operational device authentication information with fogLet identification information to a third party tenant application, the third party tenant application validating industrial data streams from the operational technology devices by communicating the operational device authentication information with the fogLet identification information to a third party cloud application.
