By the study of Li-Hwang's three-factor authenticated key agreement protocol, we find there exists multiple attack in it. Therefore, this paper proposes a remote user authentication protocol based on ECC to improve the protocol. The new protocol only needs one point multiplication of elliptic curve cryptography in login and authentication protocol, so its computation efficiency is high. The pro...

The Session Initiation Protocol (SIP), which is becoming the de facto standard for the next-generation VoIP networks, is currently receiving much attention in many aspects. One aspect that was not deeply addressed in the original SIP is its authentication procedure. Apart from its security, an SIP authentication procedure should be e cient. This paper proposes a robust and e cient three-party S...

The protocol design for wireless roaming authentication is challenging because of the key management regarding users and home/visited networks. In this paper, we present two authentication methods that demonstrate better performance in terms of authentication latency and energy consumption of a mobile terminal, compared to the 3G cellular network approach of home network transporting authentica...

Many group-oriented applications require authenticating the source of the received traffic, such as broadcasting stock quotes and videoconferencing and hence source authentication is a required component in the whole multicast security architecture. As multicast groups size may be very large and the exchanged data volume may be important (streaming), a source authentication scheme should take i...

Most authentication schemes are using physical token such as smart cards to restrict services. Although these schemes have been widely deployed for various kinds of daily applications; there are severe challenges regarding their infrastructure requirements and security. This paper proposes an efficient authentication protocol based on user’s machine-metrics. The proposed protocol uses the machi...

The multi hop mesh networkan extension of wireless mesh network by ad hoc networkis one promising wireless network architecture in the near future. Securing access network is the first protection against attacker access to network services. Authentication is an essential for securing the access to the network. TLS/SSL (Transport Layer Security/Secure Socket Layer) protocol is one famous secure ...

In this paper, we improve the GSM (Global System for Mobile Communications) authentication protocol to reduce the signaling loads on the network. The proposed protocol introduces a notion of the enhanced user profile containing a few of VLR IDs for the location areas where a mobile user is most likely to visit. We decrease the authentication costs for roaming users by exploiting the enhanced us...

This paper modifies Kak’s three-stage protocol so that it can guarantee secure transmission of information. Although avoiding man-in-the-middle attack is our primary objective in the introduction of classical authentication inside the three-stage protocol, we also benefit from the inherent advantages of the chosen classical authentication protocol. We have tried to implement ideas like key dist...
