Research On The Application Of Information Portal In Smart Residential Areas Based On Component Technology

With the concept of "smart earth" and "smart city" being put forward,the concept of smart residential areas came into being.Residential areas are basic units to bearing social population and are the micro foundation of smart cities,the construction of smart residential areas is utilized to gradually guide the realization of the smart cities and smart earth.The information portal is an important part of the informationization construction in smart residential areas and is the core of the application layer in itsinformation system.The information portal of smart residential areas is studied and applicated,and the main content of this paper is as fallow:First of all,referring on the "construction guides of green and smart residential areas in Shandong province",the actual situation of Huangjin Shanshuijun and related norms in other provinces,By analysing the construction request of smart residential areas and its integrated information service platform,the needs and main functions are determined,and the functional structure of the smart residential areas information portal is designed.Then,three kinds of software development technology is compared based on component technology.Because the Java language is platform independent and powerful,Java EE standard is selected to develop portal system.JSP+Servlet+DAO+JavaBean,the typical MVC framework,is used and some main function modules and data tables are designed.The system development environment is set up by using Apache Tomcat,Eclipse and SQL Server.And information portal is developed by Java EE component technology.Finally,aiming at the safety problems in portal,the security of the portal is studied from three aspects: user identity authentication,single sign on and data encryption.The Kerberos authentication protocol generate authentication messages to authenticate both sides of the communication and create tickets to assign session keys.As for the AES in Kerberos,the simplest matrix in the finite domain is used to replace the original,and the table look-up method is used to replace the original matrix multiplication in the algorithm,and based on work before,the encryption and decryption process is merged.As a result,not only the decryption time but also the encryption time is decreased,and at the same time the performance of the portal is improved.
