METHOD FOR ELECTRONICALLY CERTIFYING INTERNET SERVICE USE THROUGH SERIAL NUMBER OF STORAGE DEVICE AND ENCRYPTION KEY USING CONNECTION TIME

摘要

PURPOSE: A method for electronically certifying Internet service use through a serial number of a storage device and an encryption key using a connection time is provided to receive certification by using the serial number of the storage device such as an HDD or a USB(Universal Serial Bus) memory, and generating/using the encryption key with use of the latest connection time of a client. CONSTITUTION: The serial number of the storage device fixed by the client is utilized to a security certification means. The last connection time of the client is stored to the storage device fixed by the client and is used as the encryption key. For security connection of the client, the encryption key is transmitted to a server and is compared with a connection time value stored in a member record of the server after decryption. The dynamic certification key value is generated/updated/utilized to the security certification means.
