Abstract

Internet Telephony services offer several new business opportunities to telecommunication providers. However, they also introduce several security flaws that can be exploited by various attacks, thus raising the need for the employment of suitable security measures during the provision of the service. Signaling attacks, a type of Denial of Service attacks, are an indicative example. In this paper we present a cost-effective mechanism, namely the Integrity-Auth mechanism, for protecting SIP-based telephony services from signaling attacks. The focus is on the evaluation of the mechanism in terms of the processing overheads that it introduces in various different scenarios.
