Research On Information Security Of The SARFT Encryption Video System

As one of the main branches of quantum information processing technology,quantum communication has been known by a great deal of people due to its theoretical unconditional security.However,some technical requirements can not guarantee to be implemented perfectly in actual scenes,there are still security risks hidden in quantum communication systems which have been put into practical use,so it is of great directive significance to evaluate the safety performance of quantum communication systems accurately and reasonably.Currently,the assessment of safety performance of the quantum communication systems mostly stays on a rough quantitative level,or directly using the established general information system safety assessment criteria.However,if we need to get a more accurate result of evaluation,we should use a set of new assessment rules which are specially suitable for quantum communication systems to evaluate the security of quantum communication systems,and avoid to use existing assessment criteria directly.In view of this,the main work is as follows:(1)Put forward an assemblage of safety assessment indexes which is specially suitable for quantum communication system and plans 5 abstract security requirements and 38 evaluation assessment indexes through the research on quantum communication systems' working principle,physical architecture,security features and other aspects,then we simplified the assemblage through the rough set theory.(2)Based on the evaluation index assemblage above,designed an evaluation index system with weight using analytic hierarchy process,established the information security measurement model aimed at quantum communication systems using fuzzy comprehensive evaluation and gray clustering respectively,then compared and analyzed the results of the measurement models using standard deviation and discrimination.(3)Simulated and implemented the process of the weight setting and the security measurement models above in MATLAB environment,then developed a security evaluation program with simple graphical interfaces by Java.Through the work of the build and simulation of the models,solved the problem to a certain extent that the security of quantum communication systems in practical application is difficult to be evaluated quantitatively,and provided some references for the development of quantum communication system in security level.
