DES算法在自行车租赁系统中的应用

公共自行车租赁系统已逐步纳入城市公共交通体系,以解决公交出行“最后一公里”问题。本文针对自行车租赁系统中的安全认证问题,提出用软件模块实现DES算法代替传统所使用的PSAM(Purchase Secure Access Module)硬件卡方案,分别在自行车租赁系统内的售卡系统、消费终端和车辆信息几个模块中,实现DES加密。不仅提高现有系统智能卡的扩展性和安全性,而且减少硬件成本,提高了系统的效率。

DES Algorithm Used in Bicycle Rental System

Public bicycle rental system has been gradually incorporated into the urban public transport system, bus travel in order to solve the "last one kilometer" problem.In this paper, bicycle rental system security certification issue, DES algorithm in software modules instead of traditional PSAM hardware card scheme used, respectively, in the bicycle rental system Vending systems, consumer vehicle information terminal and several modules to achieve DES encryption.Not only to improve the scalability and security of the existing system of smart cards, and reduce hardware costs, improve the efficiency of the system.
