<p>The present invention relates to a security system, and more particularly, to a security system and method using a one-time execution code in an environment in which a client and a server are connected through a network. The server irregularly generates and transmits the one-time execution code to the client, and the client directly executes the one-time execution code on a memory area and transmits the execution result and deletes the one-time execution code on the memory area. Therefore, the server determines whether or not an error exists in the execution result and can prevent forgery and appropriation of the client by blocking the connection with the client.</p> |
