摘要:
城市轨道交通门禁系统通常采用的Mifare 1技术因被破解而存在严重的安全隐患,且随着城市轨道交通在各个城市的快速发展以及轨道交通运营管理部门的人员流动需求,各条线路的门禁卡需进行统一的授权管理。提出采用CPU卡技术、运用加密算法的方案,实践证明将可有效地解决上述两个问题。通过对门禁系统技术的分析,提出城市轨道交通门禁系统的技术方案,并从卡的类型、通信原理及加密可靠性等角度,研究分析其特点;论述了城市轨道交通门禁系统的加密方案及发展方向。
Abstracts:
At present, the access control systems usually adopt Mifare 1 card technology, which has been cracked and exposed to serious security risks. With the rapid network development of rail transit in Chinese cities and the urgent personnel flow demands of rail operation management departments, each rail transit line needs an unified authorization management of access card. For this reason, a scheme of adopting CPU card technology and using encryption algorithm is proposed, which will effectively solve the above-mentioned problems. In this paper, through analyzing the access control system technology, a technical scheme of access control for urban rail transit is put forward. Then, from the viewpoint of card type, communication principle and encryption reliability, the characteristics of the new scheme is analyzed. Finally the encryption scheme of access control system and the development direction in urban rail transit are discussed.
