AES加密的WiFi安全智能签到系统的设计与实现

Design and Implementation of WiFi Security Intelligent Check-in System Encrypted by AES

针对现有的基于WiFi签到系统只考虑系统设计及功能实现,未考虑到数据的安全传输问题,提出利用随机数加时间戳作为密钥,使用AES算法加密服务器之间的通信数据,保证无线控制服务器、认证服务器及签到服务器间个人信息的安全传输。最后,利用微信向客户端发送签到信息。实验结果表明,服务器端能够精准地获取客户端的签到时间、地点及个人信息,保证了师生信息的安全。

Aiming at the fact that the existing WiFi-based check-in system only concerns system design and function realization,but hardly considers the problem of data security transmission,this paper proposed using random number plus time stamp as key and using AES algorithm to encrypt communication data between servers,so as to ensure the secure transmission of personal information among wireless control servers,authentication servers and check-in servers.Finally,we used Wechat to send check-in information to the clients.The experimental results show that the server can accurately obtain the check-in time,place and personal information of the clients,which ensures the security of the information of teachers and students.
