<p>The present invention relates to an authenticating method using a security token, a system, and a device therefor, especially capable of improving security from cookie hijacking by performing authentication through the verification of a security token to which bidirectional encryption is applied when re-login for the use of a service on the web is performed. Moreover, as an authentication value forming the security token is changed by applying various operation methods, the stability of an authentication process is guaranteed. And as to security or authentication information exposed in an authentication process of a cookie method, the token length, data loss, and usage are reduced and the data transmission and movement speed are improved.</p> |
