Zfone: a New Approach for Securing Voip Communication
Zfone: A New Approach for Securing VoIP Communication Samuel Sotillo [email protected] ICTN 4040 Spring 2006 Abstract This paper reviews some security challenges currently faced by VoIP systems as well as their potential solutions. Particularly, it focuses on Zfone, a vendor-neutral security solution developed by PGP’s creator, Phil Zimmermann. Zfone is based on the Z Real-time Transport Protocol (ZRTP), which is an extension of the Real-time Transport Protocol (RTP). ZRTP offers a very simple and robust approach to providing protection against the most common type of VoIP threats. Basically, the protocol offers a mechanism to guarantee high entropy in a Diffie- Hellman key exchange by using a session key that is computed through the hashing several secrets, including a short authentication string that is read aloud by callers. The common shared secret is calculated and used only for one session at a time. However, the protocol allows for a part of the shared secret to be cached for future sessions. The mechanism provides for protection for man-in-the-middle, call hijack, spoofing, and other common types of attacks. Also, this paper explores the fact that VoIP security is a very complicated issue and that the technology is far from being inherently insecure as many people usually claim. Introduction Voice over IP (VoIP) is transforming the telecommunication industry. It offers multiple opportunities such as lower call fees, convergence of voice and data networks, simplification of deployment, and greater integration with multiple applications that offer enhanced multimedia functionality [1]. However, notwithstanding all these technological and economic opportunities, VoIP also brings up new challenges. -
