[Abstract]:Intelligent oil field is a closed-loop management which combines modern Internet of things and cloud computing technology on the basis of digital oil field, through real-time monitoring, real-time data automatic acquisition, real-time analysis and interpretation, and decision-making and optimization. The automatic production, scientific analysis and decision-making of oil field are realized, the speed and accuracy of decision-making are improved, and the purpose of efficient management of oil-gas production is achieved. Intelligent oilfield system is a set of mobile intelligent solutions, according to the deployment of a large number of mobile intelligent terminals and sensors, form a huge Internet of things, with the help of the powerful computing power of cloud computing center, Adjust production status in time after real-time analysis of collected data, and make decision support to production planning. A large number of real-time data transmission and processing requirements and the sensitivity of the special industry in which oil fields are produced determine the high dependence of intelligent oil fields on robust network connectivity. According to the current development of the Internet and the actual needs of the intelligent oilfield business, combined with some open source software development experience, the team developed a IPv6 protocol stack, which has perfect function, rapid response and can guarantee the security of the network layer connection. The actual work of this paper is to complete the IPsec part of the IPv6 protocol stack, and provide the network layer security for the data transmission of mobile terminal and network layer. The combination of IPsec and other IP packet processing modules in the protocol stack is conducive to accelerating the processing speed of packets and reducing the difficulty of system design according to the actual business needs and operating environment constraints. The main contributions and work plans of the paper are as follows. Firstly, the IPv6 protocol and IPsec protocol system are analyzed. The structure of basic header and extended header in IPv6 network layer protocol is studied because the part of IPsec security protocol packet is inserted in IP packet in the form of extended header. At the same time, the whole protocol architecture of IPsec is analyzed, and two security protocols, AH and ESP, tunnel mode and transmission mode, key exchange protocol IKE and security alliance are studied in detail. Secondly, the paper puts forward the modular design scheme of IPsec system. By classifying the functions of each part of IPsec system into functional modules with low correlation degree between each other, the coupling degree of each part of the system is reduced and the workload of system development is reduced. It is conducive to future functional expansion and maintenance of existing functions. Finally, according to the previous analysis and design, the IPsec system is implemented, and the system is tested from two aspects: function and performance. The test results show that the system achieves the design expectation and can be put into practical use.
