The last years, the trend within that industry is to integrate digital technologies in the oil and gas extraction processes as ICT performance has increased and the price has declined. As effect, the productivity of the industry has increased by using digital technologies as IoT, cloud computing, industrial internet, artificial intelligence, block-chain etc. This paper highlights IoT approaches and solutions that could be applied in the oil and gas industry in creating new value in information generated by IoT infrastructures by integration the sensor data, communication channels and data analytics. Large variety of IoT deployments and protocols raises the IoT security assurance way. In this sense, the paper provides security solutions and examples. Keywords: IoT, IoT Cloud Service, HTTP-REST API, Cyber Security, Cryptographic Security Introduction Industry 4.0 and Internet of Things – IoT are new terms on hype these days and in the market more solutions appear in the field of these buzzing words. According with Wikipedia [9], “Industry 4.0 is a name for the current trend of automation and data exchange in manufacturing technologies. It includes cyber-physical systems, the Internet of things, cloud computing and cognitive computing. Industry 4.0 is commonly referred to as the fourth industrial revolution.” Fig. 1. Industry 4.0 Phases [9] The Industry 4.0 revolution applied into Oil and Gas field, involves the improvement of the existing SCADA systems and specific filed bus communications protocols (e.g. OPC) with Internet of Things and Cloud computing technologies, in order to provide 1
