Secure and Efficient SIP Authentication Scheme for Converged VoIP Networks
نویسندگان
چکیده
The Session Initiation Protocol (SIP) is commonly used to establish Voice over IP (VoIP) calls. Mostly recently, Yoon et al. proposed a new secure and efficient SIP authentication scheme in a converged VoIP network based on ECC. In this paper, we first demonstrate that the recently proposed SIP authentication scheme is insecure against off-line password guessing attacks. Thereafter, we propose an enhanced SIP authentication scheme that enjoys provable security. And yet our scheme is simple and efficient. Therefore, the end result is more suited to be a candidate for SIP authentication scheme.

A secure and efficient SIP authentication scheme for converged VoIP networks
Session Initiation Protocol (SIP) has been widely used in current Internet protocols such as Hyper Text Transport Protocol (HTTP) and Simple Mail Transport Protocol (SMTP). SIP is a powerful signaling protocol that controls communications on the Internet for establishing, maintaining and terminating sessions. The services that are enabled by SIP are equally applicable to mobile and ubiquitous c...

Voice over Internet Protocol (VoIP) has received much attention and has became a real competitor to traditional Public Switched Telephone Networks (PSTNs), where the Session Initial Protocol (SIP) is widely used as a signaling protocol based on HTTP-like request/response exchange to establish multimedia sessions in both wireline and wireless world. However, the original authentication scheme fo...
