| With modern transportation industry and the rapid development of information technology deepening of the work, to carry out all kinds of information systems to meet business needs emerged, to improve services and transportation industry has made tremendous contributions to the management level. At the same time, the transport sector is characterized by mobility, accelerating the integration process transportation, making information systems provinces and cities, the demand for cross-regional data exchange has become increasingly urgent. However, due to the construction era, different investment costs and other reasons, resulting in various types of business information systems at the application level of security there are obvious differences, if blindly running on a network can easily lead to information eavesdropping, tampering, camouflage and other security issues. How does not affect existing business system case, less the cost to achieve improved networked data security issues, has become the transportation industry informatization development problems to be solved.Information security issues can not be isolated to solve, it relates to each of the access system, the need to design a whole, for the transportation industry digital signature system is positioned as the industry application security support systems, through digital certificate technology, to provide a unified business system digital signatures and digital envelopes services to solve the system interconnection, critical data authentication, integrity, privacy and security issues such as anti-repudiation.In this paper, SOA(service-oriented architecture) model, using JAVA language to write, using SSH architecture to design a system to achieve loosely coupled relationships with business digital signature system, system takes full advantage of the transport sector has been a CA system resources, business-oriented systems provide digital signatures and digital envelopes services, enabling business data security. Management, the use of B/S mode, the digital certificate-based strong authentication, to realize the system convenient and security management. I hope this software for the design and development of the transport sector to the business systems running on a network has played a helpful role in order to contribute^to information security in the transportation industry smoothly. Developing a business system that meets industry characteristics, but also has versatile safety support system is not an easy task, it takes time to complete, and requires a lot of research needs and trimming and perfect the system, the only way to make software systems more practical. |
