Abstract
Disclosed are an authentication system and method thereof for a dial-up networking connection via a terminal. The authentication system includes a terminal for snooping an authentication request packet that includes an authentication ID and password of a computer requesting authentication, and for generating an acknowledge packet of the authentication request packet. The authentication method includes receiving an authentication request packet including an authentication ID and password by a terminal, generating an acknowledge packet by the terminal, and transmitting generated acknowledge packet from the terminal to the computer.
Claims20
An authentication system for a dial-up networking connection via a terminal, the system comprising:
- a computer for providing an authentication request, wherein the authentication request comprises an authentication ID and a password, and for communication with a network;
- a terminal for receiving the authentication request, wherein the terminal generates a first acknowledgment responsive to the authentication request, wherein the terminal transmits the first acknowledgment to the computer, and wherein the terminal retransmits the authentication request.
A terminal for authenticating a dial-up connection between a computer and a network wherein the computer provides an authentication request comprising an authentication ID and a password, wherein the terminal compares the authentication ID and a password with a list of previously stored authentication IDs and passwords;
- and wherein the terminal generates a first acknowledgment responsive to the authentication request when the authentication ID and the password are contained in the list of previously stored authentication IDs and passwords.
An authentication method for a dial-up networking connection via a terminal, the method comprising:
- receiving by a terminal, an authentication request including an authentication ID and password from a computer that requests the authentication;
- generating by the terminal, a first acknowledgment responsive to the received authentication request;
- and
- transmitting by the terminal, the generated first acknowledgment to the computer.
An terminal authentication method for a dial-up networking connection, the method comprising the steps of:
- receiving an authentication request including an authentication ID and password from a computer that requests the authentication;
- determining whether the authentication ID and password of the received authentication request exist in a list of previously authenticated IDs and passwords stored in a nonvolatile memory;
- generating a first acknowledgment with respect to the authentication request when the authentication ID and password of the received authentication request already exist in the list of previously authenticated IDs and passwords;
- storing the authentication ID and password of the received authentication request packet in the nonvolatile memory when the authentication ID and the password are not contained in the list of previously stored authentication EDs and password;
- transmitting the generated first acknowledgment to the computer;
- forwarding the authentication request packet to a network;
- receiving a second acknowledgement generated by the network;
- discarding the second acknowledgment when the received second acknowledgment is positive;
- and
- terminating a call request of the computer when the second acknowledgment is negative notifying the computer that the second acknowledgment is negative.
