公用事业自动化收费系统数据安全性的研究

该文简要介绍了公用事业自动化收费系统的基本构成,并就系统的数据安全性进行讨论,提出了一个以随机数确定数据传输顺序,插入无效随机数增大信息冗余,用哈希函数校验,用一次性加密方法加密哈希值和随机数的数据安全解决方案,有效防止系统数据遭受主动攻击。

Study of data security in fee data automaticity collecting system of public utility

The structure of fee data automatically collecting system in public utility is introduced. With the stuty of the security of the system, a synthetic security scheme is put forth, which is using random number to decide the sequences of the data to be transmitted, inserting random numbers with no use to improve information redundance, using monodirectional hash function to get the exclusive value of the transmitted data and adopting the one time encrypt to encipher the hash value and the random number. This method is simple and highly efficient.
