Based On The Study Of Pairs Of Nuclear Safety System And Auxiliary Nuclear Hardware Architecture And Realization

With the development of Internet technology, computer network has becoming an essential part of people's life. Meanwhile, information security is becoming particularly important in national critical fields and national defense system. Currently, the majority of Operating System is Windows in China, but it has intrinsic flaws, which makes it difficult to protect the Internet safety in the country. Therefore, it is particularly vital to carry out researches on protective measures based on Windows terminals.Based on the analysis and research for hardware architecture of PC and hardware architecture of ARM, the paper proposes a security system model, based on principal-auxiliary dual-core, and provides the working principles of the dual-core security system and the hardware frame structure of the auxiliary core.In accordance with the composition of the auxiliary core hardware frame structure, the paper designed four implementation schemes in different combination modes, and analyzed the merits and defects of each one. With the requirement of the research topics, the first scheme was chosen to be brought into practice,with the mothed of "attachedboard + motherboard" and the procedure of "first test ,second implementation".Firstly,we produced a test board, to verify the feasibility of the hardware framework of the auxiliary core of the dual-core security system. Sencondly, on the basis of the testing results, by integrating, the prototype system of the auxiliary core hardware framework was realized and the moldboard was manufactured. Based on the successful manufacturing, the moldboard was optimized in level match way, in PCB board size way, and in transmission speed way, making three optimized moldboards. Lastly, the paper lists the technical problem and the solution in the process of the production.Proved by the experiments, the auxiliary core hardware platform described in the paper can not only guarantee smooth net information exchanges, but also provide a reliable hardware surroundings for the filter programs under Linux, which achieves the objectives of the project designation.
