The Design And Implement Of IPsec Protocol In Mobile Teminal For Smart Oilfield

Smart oilfield has grown from digital oilfield, combined with modern Internet of Things and cloud computing technology, through the closed-loop management of real-time monitoring, real-time automatic data acquisition, real-time analysis and interpretation, implementation and optimization of decision, automation production and scientific analysis improves decision-making speed and accuracy, so as to achieve the purpose of efficient management of oil and gas production. Smart oilfield system is a mobile intelligent solutions, based on a large number of mobile intelligent terminals and sensors deployed, forming a huge Internet of Things, cloud computing center by means of powerful computing capability, timely adjustment of status after the production of real-time analysis of the collected data, support for production planning decisions. Sensitive real-time transmission of large amounts of data and processing requirements determines the smart oilfield is highly dependent on robust intelligence network connection. Task Force based on the current situation and the need to develop practical smart oilfield operations of the Internet, combined with a number of open source software development experience, has developed a fully functional, responsive IPv6protocol stack, this stack is able to guarantee the security of the network layer connection.The actual work of this paper is to complete the IPsec part of IPv6protocol to support mobile terminal for data transmission under network-layer security protection. According to the actual business needs and operational constraints, the IPsec combined together with other IP packet processing modules in protocol stack to speed packet processing speed and reduce the difficulty of system design. The main contribution of the paper and work plan in the following points.Firstly, we analysis the IPv6protocols and IPsec. We studied the structure of IPv6network layer protocol packet header and extension headers, because IPsec security protocol packet inserted into IP packet as an extension header. And then the analysis the entire IPsec protocol architecture is provided. The analys is focusing on the AH and ESP security protocol, tunnel mode and transport mode, and key exchange protocol IKE and security association.Secondly, the paper presents a modular design IPsec system, each part of the IPsec system are classified into modules which is low correlation with each other according to features, thereby reducing the degree of coupling between the various parts of the system, reducing the system development effort conducive to future functionality expansion and maintenance of existing functionality.Finally, based on the preceding analysis and design, we implement the IPsec system, and the system has been tested both from the functional and performance side. The test results show that the system meets what it is expected to achieve and can be put into practical use.
