## 5 Conclusions and Prospects  
The maritime data security management platform is developed by referring to the CSSA shore-based system architecture and the MSP information service system, and the four-layer software architecture is designed according to the J2 EE technology architecture. Through the integration, processing and analysis of the electronic navigation chart, marine environment, AIS and other data, ship navigation information, ship dynamic information, maritime security information and other information services are realized. This platform integrates multi-source heterogeneous data, a navigation application model and an electronic navigation chart. It solves the problems regarding the lack of maritime security information, complex navigation tools and overlapping functions. The integrated maritime security information system has been realized, which enhances the ability of safe navigation of ships, shares navigation information more widely and comprehensively and makes the operation of navigators more convenient and fast. At present, three application systems have been developed based on the platform architecture, which can give full play to the advantages of unified data management and provide users with various services of MSP such as geographic information, environmental information and navigation information.  
The maritime data security management platform will still face many challenges, and future work will focus on the improvement of system functions and application promotion. Although the platform has realized a comprehensive display of maritime

security information, there are still difficulties in data coordination and sharing among various maritime departments, so it is necessary to design a unified platform conducive to the management of various maritime departments. Besides, the expression of data under the S-100 standard is not perfect, especially the lack of intelligent performance of three-dimensional navigation data, and a mature software system has not been formed.  
There are still many challenges in developing the maritime data security management platform. However, this study demonstrates this platform can provide promising applications for the field of e-Navigation Test Beds.
