CHARIOT will advance state of the art by providing a design method and cognitive computing platform supporting a unified approach towards Privacy, Security and Safety (PSS) of IoT Systems, that places devices and hardware at the root of trust, in turn contributing to high security and integrity of industrial IoT. More specifically, for each of the PSS ‘imperatives’, a highly innovative approach is proposed as follows:

• A Privacy and Security Protection method building on concepts from state-of-the-art Public Key Infrastructure (PKI) technologies, to enable the coupling of a pre-programmed private key deployed to IoT devices with a corresponding private key on Blockchain system for the purposes of affirming and approving valid transactions. 
  
• A Blockchain ledger in which categories of IoT physical, operational and functional changes are both recorded and affirmed/approved through a combination of coupling a cognitive engine and private key hashing between the cognitive engine and IoT devices to authorise change and, likewise, invalidating any and all other changes whether malicious or otherwise. Such a ledger provides a compelling journal and audit log from which, through machine learning, past patterns can be used as a basis to highlight present anomalies and inconsistencies and, in turn, halting execution in situations where transactions and workflows deviate from established patterns of behaviour. 
  
• A fog-based decentralised infrastructure for Firmware and Operational Security integrity checking that leverages a Blockchain ledger to enhance physical, operational and functional security of IoT systems, such as actuation, deactivation, transactions of all types including business process workflows and their associated business logic. 
  
• An accompanying IoT Safety Supervision Engine providing a novel solution to the challenges of securing IoT data, devices and functionality for new and existing industry-specific safety critical systems. 
  
• A Cognitive System and Method with accompanying supervision, analytics and prediction models that encapsulates these latter capabilities, with the end goal of high fidelity security and integrity of Industrial IoT. 
  
• New methods and tools for static code analysis of IoT devices, resulting in more efficient secure and safer IoT software development and V&V. 

The “CHARIOT IoT Search Index” aims to provide a web location where publications, articles, and relevant documents can be centralized hosted in a well-structured and easily accessed way.
