Research And Implementation Of Iptv Digital Rights Management Technology

For a long time,the security issue has been the focus of the entire civil aviation industry,and whether the whole air transport industry can achieve a rapidly,healthy and sustainable development,security has played a decisive role.In order to provide a better aviation security services,China's civil aviation in accordance with the requirements of the international civil aviation organization,in the civil aviation industry to promote the construction of the Security Management System(SMS),and it includs the construction of safety management information.According to the above proposed target,and In the combination of civil aviation science and technology institute of China airlines and airport aviation safety management system construction situation of investigation,each unit of SMS still exist many problems,including:the guide files are too theoretical,and lack of effective tools to make a comprehensive analysis in the construction of SMS.It cannot find the weakness in the process of construction;Safety management of the software system has yet to be perfect and the informationization level is not high enough;Safety information,especially the hazard information management is simple,these enterprises cannot understand hazards information,unable to further back;To collect the information cannot be in-depth analysis and mining.It can't play to the role of the trend prediction and can't work to carry out targeted.Faced with the above problems,this paper takes the evaluation of enterprise SMS construction as the breakthrough point,focusing on the completion of the Security Management System audit system development.The main content is:(1)In-depth research the SMS-AS is the core of the management requirements.On the basis of this,detailed analysis of the SMS-AS of various functional requirements;(2)Proposed SMS auditing system design;(3)Completed the SMS-AS in each module programming essential technology implementation and testing.In this paper,the construction of the SMS indicators modeled form checklist,designed and implemented an auditing system for certain sensitive information,and create and modify the checklist,create auditing tasks,assign groups,conducting audits,statistics,data display workflow automation.The system uses C/S layered architecture,complete user authentication and rights management,database design and handwritten signature authentication and other functions,has a good scalability,and focuses on the encryption/decryption heterogeneous transmission between terminal equipment,design and implementation of heterogeneous database data exchange and high concurrent network transmission.On the one hand,it is possible for SMS construction enterprises to conduct a comprehensive assessment at this stage is very practical,on the other hand,it is based on the assessment results and safety information collection,statistical analysis,made in the trend projections a preliminary attempt and exploration.
