    • PROBLEM TO BE SOLVED: To facilitate client management at an access protection target device side by eliminating spoofing at the time of client authentication. SOLUTION: A server 14 being an access protection target transmits an authentication information request A2 when an access request A1 is made from client communication equipment 11, and transmits authentication information A3 from the client communication equipment 11 to network connection equipment 12 (A4). The network connection device 12 performs the authentication processing of authentication information A4 based on the communication and connection information of the client communication equipment 11, and notifies the server 14 of the identification processing result A5. The server 14 determines whether or not the client communication equipment 11 being the access origin is a normal user from the authentication processing result A5, and when the client communication equipment 11 is the normal user, the client communication equipment 11 is connected to a line so that a communication enabled state can be set (A6).

    • 要解决的问题:通过在客户端认证时消除欺骗,便于访问保护目标设备端的客户端管理。 解决方案:作为访问保护目标的服务器14当从客户端通信设备11进行访问请求A1时发送认证信息请求A2,并将来自客户端通信设备11的认证信息A3发送到网络连接设备12(A4 )。 网络连接装置12基于客户通信装置11的通信和连接信息进行认证信息A4的认证处理,并向服务器14通知识别处理结果A5。 服务器14从认证处理结果A5判定作为访问来源的客户端通信设备11是否为普通用户,当客户端通信设备11是正常用户时,客户端通信设备11被连接到线路 可以设置通信使能状态(A6)。 版权所有(C)2005,JPO&NCIPI
