A survivability evaluation model method based on a BP neural network wide area information management system

Abstract

The invention discloses a survivability assessment model method based on a BP neural network wide area information management system, and relates to the field of civil aviation information system safety. The method can help civil aviation related departments to make accurate assessment, guarantees the safety and quality of aviation operation, and lays a foundation for construction of a safe air traffic management information interaction platform. The survivability of a wide area information management system (SWIM) is a new direction for civil aviation research, a SWIM survivable PDRRDR modelis constructed, a three-layer relation corresponding to the SWIM survivable PDRRDR model is established by adopting a BP neural network method, and the survivability of the SWIM is evaluated and verified. The provided SWIM survivable PDRRDR model and evaluation method are good in adaptability, high in fault-tolerant capability and efficient and accurate in evaluation, an effective scientific meansand tool are provided for complex SWIM survivability evaluation, continuity of civil aviation safety in China is guaranteed, and the method has important significance for development of air traffic management of the next generation of China.

Description

technical field [0001] The present invention relates to an aviation network information system security technology, especially for evaluating and verifying the survivability of a wide-area information management system (System Wide Information Management, SWIM), which improves the efficiency and reliability of the evaluation and makes the results more objective. Help the relevant civil aviation departments to make accurate assessments, so as to ensure the continuity of my country's civil aviation safety. Background technique [0002] The basic concept of SWIM is to maximize the use of SWIM to enable all participants in air traffic management to share the latest information of all parties at the same time, so as to ensure that the relevant information of relevant civil aviation units such as air traffic control departments, airlines and aviation airports can be shared safely, effectively and in a timely manner And exchanges, so as to carry out timely and accurate collaborative...

Problems solved by technology

However, the main problems it faces are: the existing service drift strategy is limited to the service provider, lacking consideration for changes in the external network environment and customer needs, and the long-term single process migration mode is easy to be seen through by attackers, reducing the risk of service drift Effectiveness; the state of the service is not classified and analyzed in detail, only the execution state of the process on the virtual machine is obtained and restored; there is no unified understanding of the research on the service migration mechanism

[0004] Network survivability research is a new direction for the development of network security technology at home and abroad. Some achievements have been made in the research of emergency response to large-scale networks and information systems, but the research on SWIM survivability is still in its infancy. SWIM's The basic theory of structure, service and security is lacking, and the research on key technologies is not deep enough, especially in SWIM survivability assessment, there are few existing research results, and there is a lack of reasonable implementation plans and effective methods
