Trusted Technology And Evaluation Method Based On Virtual Instrument For Networked Measurement And Control

With the title of"Trusted Technology and Evaluation Method Based on Virtual Instrument for Networked Measurement and Control", the trusted technology and VINMCP(Virtual Instrument for Networked Measurement and Control Platform) are studied in the thesis, which has important academic value and practical significance in promoting the development of trusted technology in VINMCP study and Subject of Measuring and Controlling. This paper is supported by the Natural Science Fund of Guangdong Province (9151007010000001) and the Program for New Century Excellent Talents in University of Ministry of Education (No.NCET-08-0211).Measurement & control platform for virtual instrument network are summarized and systematically analyzed; meanwhile, the research situation of technology of integrity verification, identity authentication, data protection, that is closely associated with VINMCP and Trusted Technology, is discussed in the thesis. Integrated with the Trusted Technology above, the overall architecture of VINMCP is modeled, characteristics, function requirements, integrity verification requirements, identity authentication demand and data protection need of which are discussed. Detailed analysis and design are made for function module of VINMCP, of which evaluation and test method of function, performance and credible are put forward. Main work of this thesis include:①Basic function requirements and corresponding credible demand of VINMCP is analyzed. The overall architecture of VINMCP is modeled, of which relative characteristic is probed. It is pointed out that VINMCP modeling is the key in the area of trusted technology and the function of each component modules is interpreted. Finally, design of each relevant function module is provided.②Trusted technology includes Integrity verification and use-control.③Integrity verification technology is discussed .Especially, through SHA-1 workflow technology, working process of integrity verification of VINMCP is realized, at which, the realization of integrity is discussed. At the same time, aiming at concurrent integrity verification of VINMCP, the ICE technology is introduced, while concurrency control model for dealing with the concurrent integrity verification request messages is built, implementing of which discussed.④The use-control technology of VINMCP in introduced, as well as IBE, the working mechanism of which is probed, and which is used for the identity authentication technology and data protection technology. Identity authentication design and implementation of the scheme is analyzed, evaluation cases of which is provided. In the meanwhile, aiming at VINMCP, the composition and structure of sensitive datagram is analyzed based on the need of trusted technology. It is also discussed how to design and realize data protection under IBE. In the end, the used control experiments are finished in the existing system.⑤In the thesis, application of trusted technology is configured to build detection platform of virtual instrument network transmission line, and the UML needs, functional structure, the corresponding workflow and database table structure of VINMCP is put forward. Finally, according to the measurement and control the platform functional testing and performance test, in allusion to VINMCP, measurement and control tests and function tests are made to ensure the platform running smoothly.
