摘要
动态密码是当下主流的身份认证技术之一,已被行业广泛使用,并能与不同规模的业务系统快速对接,是比较高效,稳定的技术方案。本系统采用STM32F103ZET6芯片为主机、从机的核心处理器,以RBAC权限模型为基础,采用动态密码登录方式,由用户在主机输入的随机数读取存储在W25Q64中的密码表数据,并和基础密码进行加密,通过HC-05模块进行从机的密码、访问权限的设置,并在成功登录后只能进行允许的权限操作。系统安全性有了较大的提高。
Dynamic password is one of the mainstream identity authentication technologies at present.It has been widely used in the industry and can be quickly connected with business systems of different scale.It is a relatively efficient and stable technical solution.Our system adopts the STM32 F103 ZET6 chip as the core processor of the master and the slave machines,and the dynamic password login system based on the RBAC authorization model is used.The password list stored in the W25 Q64 is read by using the random number the user inputs on the master,and the password is encrypted by using the base password.The password and access permissions of the slave are set through the HC-05 module,and only the permitted operations will be allowed after successful login.In this way the system security has been greatly improved.
