The use of multi-cloud environments for chemical plants and other critical infrastructures is a growing trend that poses a considerable security problem, especially in the areas of access control and continuity of operations during low bandwidth, offline or no internet connectivity situations. This paper focuses on the evaluation of the Gros and Kerry authentication mechanism, which is a two-user authentication scheme that is aimed at increasing security in high-risk areas. This method involves the use of time-sensitive, token-based passwords and the need for two users to authenticate at the same time, thus making it very secure against token interception and replay attacks. It is worth mentioning that the Gros and Kerry mechanism is designed to work independently from the Internet connection, and this means that the critical applications will always remain secure and available even in remote situations or emergencies when all the other security measures may fail. This research validates the effectiveness of the proposed system in a simulated chemical plant environment, and its high security and operational reliability make it a suitable solution for other high-security applications. Subsequent studies will attempt to incorporate this mechanism with other technologies, such as artificial intelligence and blockchain, to enhance its functionality. Load balancing is a functionality where the system finds the failure node and rectify it by balance measures.
