Secure and efficient ECC based SIP authentication scheme for VoIP communications in internet of things

Since last decade, VoIP is transitioning from being a voice scheme to the most powerful unified communications engine. All VoIP systems uses the Session Initiation Scheme that defines the procedures and messages used to set up a phone call – or any other kind of communication. IoT is another paradigm-shifting idea that is going to change VoIP communications, since it offers a seamless way to connect all of the devices, applications and platforms. Embedding VoIP in IoT solutions provides a competitive advantage over the traditional telephony system of being interconnected to Internet of Things. With the IoT, value proposition of VoIP broadens so with IoT, however, VoIP is vulnerable to all of the intrinsic security problems in IP. In this paper, a new biometrics based authentication scheme using ECC has been proposed. The formal and informal security analysis of the scheme proves the security strength of the scheme. Simulation of the scheme using AVISPA also proves the scheme is secure against potential threats. Comparison of the proposed scheme in terms of computation cost and security features with other related schemes proves the superiority of the scheme.
