Abstract

Many real-world communication protocols in Operational Technology (OT) are prone to cyber attacks due to the absence of dedicated key exchange and inability to satisfy all key exchange properties such as mutual authentication, key secrecy, and key confirmation. Besides these deficiencies, the security of communications in the OT is severely lacking at least one of the communication security properties such as data integrity, data confidentiality, and data availability. In this paper, we propose to enhance OT communication protocols via a secure key exchange framework for satisfying the key exchange and communication security properties based on universal composability, which provides modular design and analysis of cryptographic protocols in the presence of an adversary. Our framework comprises an ideal crypto-ops functionality (F_cl) for modelling and satisfying the key exchange and communication security properties. We analyse the security of our framework using the Automated Validation of Internet of Security Protocols and Applications (AVISPA) tool. Furthermore, we illustrate the usefulness of our framework by fixing one of the most widely used real-world OT communication protocols, namely WirelessHART.
