Abstract
This paper proposes a new protection technique against deregistration attack in SIP. Although it is caused by simple spoofing the REGISTER message of a legitimate SIP UA, its impact is serious. This new protection technique identifies and protects the deregistration attack by removing a binding form the location server after delaying a certain period of time instead of removing the binding immediately after receiving deregistration message. Therefore, this technique makes it possible to establish a secure SIP environment defending the deregistraion attack without any additional overhead such as an encryption or authentication.
