Research On Security Architecture Of IoT Application Layer

The Internet of Things, the third wave of the information industry revolution following the computer and the Internet, is one of the hottest research interests in the area of communications and information. Along with the emergence of the Internet of things applications, information security issues come one after another. Users expect to get security monitoring and early warning for their own information systems, which needs corresponding security services and software to provide support and cultivating a group of professional staff to carry out related work, these all need huge investment. On the other hand, the security products are increasing, and product standards between suppliers are different, users are confronted with difficulty in choice on the issue of security products. Under such circumstances, it is particularly important to provide a set of security architecture which oriented-to internet of things application layerThis thesis begins with proposing establishing a unified security service platform to provide users with different kind of security services in answer of the situation that product standard is not unified, user’s security burden is heavy, large resource consumption, so that users can be points out from the security business, can make the application of Internet of things no longer in the isolated state and can provide different customers with convenient, fast Internet security services. On the premise of assumption, the paper conducted a deeply study and summary in service-oriented architecture, XML technologies, middleware technologies and Web service to provide technical support for the implementation of the assumption.On the basis of the analysis of security requirements, this paper puts forward the "centralized monitoring and unified management and comprehensive analysis, rapid response "security services architecture concept, which is divided into a four-layer structure than include data acquisition, data processing, data analysis, safety monitoring. This architecture has the following characteristics:low resource consumption, users achieve their security requirements by custom service to save the investment in maintenance software and training professional staff; software reuse rate is high, the same service can be used for different users,and you just need to agree that configuration information and rules; unified service management, security services architecture will enable the emergence of heavyweight security service provider, so that the product standard will be unified; strong extensibility, based on a service-oriented architecture, making the service extension and combination is possible.Finally, this paper provides a simplified example to simulate architecture which is proposed earlier. And it shows that this architecture is practicable.
