<abstract><p>Designing a secure authentication scheme for session initial protocol (SIP) over internet protocol (VoIP) networks remains challenging. In this paper, we revisit the protocol of Zhang, Tang and Zhu (2015) and reveal that the protocol is vulnerable to key-compromise impersonation attacks. We then propose a SIP authenticated key agreement protocol (AKAP) using elliptic curve cryptography (ECC). We demonstrate the correctness of the protocol using Burrows-Abadi-Needham (BAN), and its security using the AVISPA simulation tool. We also evaluate its performance against those of Zhang, Tang and Zhu, and others.</p></abstract>

Recently, several protocols came into being successively to meet the requirement of efficient operations in low-power roaming environment with the fast advance of communication technologies. Unfortunately, these protocols are not a suitable candidate for special requirements in automobile roaming system such as low consumption, high performance and convenience since these protocols pay more attention to a common network environment. In this paper, we address the problem of mutual authentication and key agreement with user anonymity for an automobile roaming system. More specifically, we propose the protocol employs elliptic curve cryptography system to enhance operational efficiency and take into account common attacks and give corresponding resist measures to ensure security. The analysis shows our scheme is user friendly and secure.
