Presentation a Model of Blockchain Mechanisms for IoT Security in the Oil and Gas Industry of NISOC

As oil and gas resources play an essential role in energy, oil and gas industry technologies have also developed rapidly in recent years, such as smart drilling technology, smart oil and gas transmission pipelines, and digital offshore platforms. The oil and gas industry has four aspects: business, management and decision-making, monitoring and cyber security. Finally, the state of application programs, the level of understanding of block chain in the security of the Internet of Things in the oil and gas industry, opportunities, challenges and risks and the development process are examined. Therefore, the main goal of the research is to provide a model of block chain mechanisms for the security of the Internet of Things in the Iranian National Oil Company. The nature of the current research is exploratory and qualitative data is used in it. The statistical population of the research is the experts and professors of doctorate in management and information technology in the oil and gas industry (NISOC). In this context, the researcher used the snowball method to achieve theoretical saturation, and the researcher achieved theoretical saturation after structured interviews with 10 elites and experts. Data analysis was done with the qualitative method of Foundation Data Theory and Maxqda2020 software. The findings indicate that the causal factors affecting the block-chain mechanisms for the cyber security of the Internet of Things in the oil and gas industry in the form of three concepts, including data aggregation and storage (network), validation and identity management and key management and data encryption were identified. Also, influential background factors include nine concepts of financial resources, management, distribution of infrastructure services, data confidentiality, system stability, scalability, accessibility, transparency, expertise. and intervening (environmental) factors include seven concepts of environment. Operational standards, standards and procedures are the nature of data for mechanisms in various industries, social environment, cultural environment, government laws and regulations, political relations and the strategies of block chain mechanisms for the cyber security of the Internet of Things, in the form of six concepts of electronic health, creating a secure layer, smart transportation, smart networks, the use of smart block chain contracts, the design of industrial Internet of Things (IIOT) devices, and the consequences And the results of the implementation of block chain. Mechanisms for the cyber security of the Internet of Things in the oil and gas industry of the National Company of the Southern Oil Rich Regions(Nisoc), including the attitude of reducing production costs, high capacity for storage, intelligent field, organizational agility, environmental dynamics, security, System accessibility, improvement of the user interface, the quality of information (distribution and variety of information) and the speed of data processing.
