网络IC卡门禁控制器基于TCP/IP网络传输数据。刷卡数据和状态数据通过以太网络传输,构成没有距离限制的、大容量的广域系统。GNC-ICT的数据传输采用了可靠的数字签名方式,刷卡认证时使用类似RADIUS认证的方式,保证了系统的安全性。网络IC卡门禁控制器具有本地认证的功能,IC卡控制器本身存储3000张IC卡的资料,当网络中断的时候可以进入脱机认证的方式,对于门禁系统可以根据存储的卡资料判断是否允许通行,并记录刷卡情况,当网络恢复的时候再将存储的脱机数据发送回中心。控制
Network IC card access controller based on TCP / IP network data transmission. Credit card data and status data are transmitted over the Ethernet and form a wide-area, wide-area system without distance limitations. The data transmission of GNC-ICT adopts the reliable digital signature method, and the authentication similar to RADIUS is used in the credit card authentication to ensure the security of the system. Network IC card access controller with local authentication function, IC card controller itself stores 3000 IC card information, when the network is out of line can enter the offline authentication mode, the access control system can be stored card information to determine whether to allow Traffic, and record credit card situation, when the network is restored, then store the offline data back to the center. control
