【摘要】：随着智慧地球和智慧城市的概念先后被提出,智慧住区的概念应运而生。住区是承载社会人口的基本单元,是智慧城市的微观基础,通过智慧住区的建设,可以逐步引导智慧城市和智慧地球的实现。智慧住区信息门户是住区信息化建设的重要组成部分,是智慧住区综合信息服务平台的应用层核心。本文对智慧住区信息门户进行了应用研究,主要内容如下:首先,从《山东省绿色智慧住区建设指南》和黄金山水郡智慧住区项目实际情况出发,参考各地智慧住区建设相关规范,分析了智慧住区及智慧住区综合信息服务平台的建设要求,确定了智慧住区信息门户的需求与主要功能,并设计了智慧住区门户的功能结构。然后,比较了几种基于组件的软件开发规范,由于Java语言具有平台无关性且功能强大,选择JavaEE规范开发门户系统。系统采用典型的MVC框架JSP+Servlet+DAO+JavaBean进行开发,并设计了系统中主要功能模块的类图和相关数据表。采用Web服务器Tomcat、Eclipse和SQL Server搭建了系统开发环境,使用JavaEE组件技术开发了智慧住区信息门户。最后,针对门户的安全问题,从用户身份认证、单点登录和数据加密三个方面,对门户的安全进行了研究。利用Kerberos认证协议产生的认证消息对通信双方进行身份认证,实现用户的单点登录。针对Kerberos协议中的AES加密算法,采用有限域的最简矩阵代替原来算法中的矩阵,用查表法代替原来算法中的矩阵乘法,在此基础上对加解密过程进行了合并,减少了算法的耗时,改进了AES加密算法的性能,提高了门户的安全性能。
[Abstract]:With the concept of intelligent earth and intelligent city has been put forward, the concept of intelligent settlements came into being. The residential area is the basic unit of carrying the social population and the micro foundation of the intelligent city. Through the construction of the intelligent residential area, the realization of the intelligent city and the intelligent earth can be guided step by step. Intelligent residence information portal is an important part of residential information construction and the application layer core of intelligent residential area integrated information service platform. The main contents of this paper are as follows: first of all, from the "Guide to the Construction of Green Intelligent Residential District of Shandong Province" and the actual situation of the "Jinshanshui County" Intelligent Residential District Project, Referring to the relevant norms of the construction of intelligent residential areas, this paper analyzes the construction requirements of the intelligent residential areas and their comprehensive information service platform, determines the needs and main functions of the intelligent residential area information portal, and designs the functional structure of the intelligent residential area portal. Then, several component-based software development specifications are compared. Because the Java language is platform-independent and powerful, the JavaEE specification is chosen to develop the portal system. The system adopts the typical MVC framework JSP Servlet DAO JavaBean to develop, and designs the class diagram and the related data table of the main function module of the system. The system development environment is built by Web server Tomcat,Eclipse and SQL Server, and the intelligent residential area information portal is developed by JavaEE component technology. Finally, the security of portal is studied from three aspects: user identity authentication, single sign-on and data encryption. The authentication message generated by Kerberos authentication protocol is used to authenticate the communication parties and realize the single sign-on of users. Aiming at the AES encryption algorithm in Kerberos protocol, the simplest matrix in finite field is used instead of the matrix in the original algorithm, and the matrix multiplication in the original algorithm is replaced by the look-up table method. On this basis, the encryption and decryption process is merged and the time consuming of the algorithm is reduced. The performance of AES encryption algorithm is improved, and the security performance of portal is improved.
