<p>The present invention relates to a method for enhancing security related to transmission of an authentication key. According to the present invention, the method comprises: a step (a) where a server transmits a filter to a terminal device to perform an operation with an authentication key in a state where the authentication key is shared between the server and the terminal device, and where the terminal device generates a deformed authentication key by using the authentication key and the filter through a predetermined operation, and the terminal device encodes the generated deformed authentication key in order to generate a security authentication key; a step (b) where the server generates the deformed authentication key by using the authentication key and the filter included in the server by going through the predetermined operation, encoding the generated deformed authentication key to generate the security authentication key; and a step (c) where the server compares the security authentication key included in the server with the security authentication key received from the terminal device when the security authentication key is transmitted from the terminal device to the server in order to authenticate the same. Accordingly, the method of the present invention has an effect of enhancing security by preventing leakage of an entire authentication key since only a part of the authentication key is transmitted.</p> |
