<p>The present invention relates to a method for preventing attacks on a Media Gateway Control Protocol message, wherein, the method comprises the steps of : calculating the Hash value of a designated string as an attack-preventing token of a Media Gateway Control Protocol message to be sent by a first device (10) to a second device (20), wherein said designated string is formed by a cipher key shared between said first device and said second device, an identifier of said first device (10) and said second device (20) as a media gateway device, and said Media Gateway Control Protocol message; and wherein said attack- preventing token will be sent together with said Media Gateway Control Protocol message to said second device. By using the method, attacks on the Media Gateway Control Protocol, which do not provide security mechanisms, can be reduced or avoided.</p> |
