A method for providing online/offline linked education with a USB(Universal Serial Bus) device is provided to remove a process for downloading/installing a program, and prevent separation between online and offline education by automatically storing/updating data needed for an offline education process to the USB device including an education program, and performing learning continuously in any place while carrying the USB device. An academy manager requests an issuance key by inputting user information to an authentication server(131). The authentication server generates the issuance key in a random number mode, and a manager server stores the issuance key to a USB device of a user(221). The user is authenticated by inputting the issuance key to the authentication server. An authentication key is inputted and generated to issue a certificate(132). The issued certificate is stored in the USB device of the user. The user is authenticated in a lecture management system operated in a workstation of an academy by using the certificate. The user enters a lecture room and waits for a lecture. Multimedia text is executed in a lecture screen by remote control of a lecturer PC. Te user evaluates the lecture and transmits evaluation data. |
