【摘要】 LON总线技术是当今炙手可热的自动化技术，已经被广泛应用在楼宇自动化、智能小区、交通运输、工业控制等领域。智能卡技术在智能小区中的应用也是如火如荼。如何把LON总线技术和智能卡技术集成为一个成本低廉、自动化程度高和安全可靠的系统，是许多企业竞相研发的一种重要技术，也有着广泛的应用前景。 论文首先概括性地介绍了智能小区的概念以及LON总线技术，并对LON总线技术在智能小区中的应用做了分析和展望。在概括性地介绍智能卡的物理结构之后，重点介绍了AT89SC168芯片的使用，智能卡的文件数据结构和卡内操作系统结构。然后论文在详细研究DES、RSA、ECC等加密算法的前提下，分析了它们在实际应用中性能上的优缺点，进而，设计了一种基于DES和ECC的混合加密体制，给出了算法的实现流程，解决了单独使用DES、RSA算法所带来的密钥保存不方便和运算速度较慢等问题，有效地提高了系统的安全性能。接着文章给出了一种基于LON总线的小区智能卡系统集成方案。该方案解决了小区产品协议多元化和面向各种应用的体系结构不匹配等问题，并使用混合密码体制提高了系统安全性。最后文章设计了一个基于LON总线的小区智能卡停车收费管理系统和门禁系统，并给出了每个系统详细的软硬件、网络设计和安全性解决措施。设计的系统具有信息综合、资源共享、物业管理集中化等特点和自动化程度高、性能稳定、高度安全等优点，使得智能小区真正达到住户安全、舒适、便捷等要求。更多还原

【Abstract】 Fieldbus is the hottest automation technology today which has been used in all kinds fields, such as building automation, intelligent region, traffic transport, industrial controlling. The technology of Smart Card has been widely applied in the intelligent region. So it is very significant to make some researches on how to integrate the LON fieldbus and Smart Card into a cheapness, higher degree of automation, higher security and credibility system.In this paper, the concept of intelligent region and the technology of LON fieldbus is generally introduced , and also analysed and prospected the application of LON fieldbus in intelligent region. After synoptically introduced the physical structure of Smart Card , the using of the chip AT89SC168 and structure on file and data of Smart Card is especially introduced. After particularly researched the cryptogram algorithm of DES,RSA,ECC,with which the virtue and shortcoming of performance in practice using is analysed. Through which a hybrid ecryptogram system based on the DES and ECC is designed, and also the flow of this cryptogram is provided. With this cryptogram, the problems of conservation of key and velocity of operation which aroses from using DES,RSA algorithm singly is it resolved,and the securities of the system is improved. Then a draft is given .With this draft, the problems of various products of region and the system structure unmatching is resolved ,and the security of system is improved by using the mix cryptogram . At last based on the LON fieldbus and Smart Card thechnology, a system of automatic charge park and door manage system is designed .The structure of network, hardware, software is particularly designed and security measure of system is given. This system has the characteristic of information synthesis and many excellences ,such as higher automatic degree, steady performance and altitudinal security. With this system,the demand of security, comfort and convenience is achieved in intelligent region.更多还原
