METHOD FOR AUTHENTICATION AND IP SPOOFING DETECTION BETWEEN WEB SERVER AND USER

摘要

PURPOSE: A method for authenticating a user terminal and a method for detecting IP spoofing using a web server are provided to verify the IP spoofing by matching an IP address from the origin of a packet and an IP address of a user which is transferred during an authentication process. CONSTITUTION: If a user terminal requires an authentication using an ID and a password, a web server transmits and installs an authentication module to the user terminal. The web server obtains the real IP information of the user terminal through the authentication module. The real IP information is compared to the IP information from the user terminal. The IP spoofing is verified based on the comparison result.
