Comparison of IPsec to TLS and SRTP for Securing VoIP

Barry Sweeney, Duminda Wijesekera

Abstract

With the IETF requirement to include Internet Protocol Security (IPsec) in every implementation of Internet Protocol version 6 (IPv6), it is prudent to consider IPsec as a viable protocol for securing IPv6 Voice over Internet Protocol (VoIP) sessions. This approach is currently inconsistent with the direction of industry, which has chosen Transport Layer Security (TLS) to secure the Session Initiation Protocol (SIP) packets and Secure Real-time Transport Protocol (SRTP) to secure the Real-time Transport Protocol (RTP) packets for VoIP sessions. A comparison of these two approaches is currently not available and this paper attempts to provide that comparison and discuss the advantages and disadvantages of each approach so that implementers and Information Assurance (IA) architects may make an informed decision. This paper is not necessarily an IA document, but is instead focused on the comparison of the two approaches based on many factors to include IA concerns.
