The security and privacy of the tag carrier has become the bottle neck of Radio Frequency Identification (RFID) system development further. In this paper, we propose a robust authentication protocol based on Elliptic Curve Cryptography (ECC), which meets the requirement of resource-limited RFID systems. Our protocol achieves mutual authentication and possesses lightweight feature by reducing th...

Authentication is an important mechanism for the reliable operation of any Voice over IP (VoIP) infrastructure. Digest authentication has become the most widely adopted VoIP authentication protocol due to its simple properties. However, even this lightweight protocol can have a significant impact on the performance and scalability of a VoIP infrastructure. In this paper, we present Proxychain –...

Password is the most commonly used authentication technique to authenticate the users on the web. Password based authentication protocols are susceptible to dictionary attacks by means of automated programs because most of the user chosen passwords are limited to the user’s personal domain. In this paper, we propose an inverse cookie based virtual password authentication protocol that preserves...

A deniable authentication protocol enables a receiver to identify the true source of a given message but not to prove the identity of the sender to the third party. Non-interactive protocol is more efficient than interactive protocol in terms of communication overhead, and thus several non-interactive deniable authentication protocols have been proposed. So, it is very necessary to design a den...

Deploying a new security protocol is expensive. This encourages system designers to look for ways of re-using existing infrastructure. When security protocols and components are re-used, it is critical to re-examine the security of the resulting system as a whole. For example, it has become a common paradigm to run a legacy client authentication protocol within a server-authenticated tunnel. Th...

The Session Initiation Protocol (SIP) protocol is commonly used to establish Voice over IP (VoIP) calls. IETF SIP standards do not specify a secure authentication process thus allowing malicious parties to impersonate other parties or to charge calls to other parties. This paper proposes an extension to the SIP protocol that uses an identity-based authentication mechanism and key agreement prot...

In this paper we analyse an anonymous wireless authentication and conference key distribution scheme which is also designed to provide mobile participants with user identification privacy during the conference call. The proposed scheme consists of three sub-protocols: the Call Set-Up Authentication Protocol, the Hand-Off Authentication Protocol, and the Anonymous Conference Call Protocol. We sh...
