Protocol and technology convergence, the core of near future communication, will soon be forming the interoperating heterogeneous networks. Attaining a strict secure authentication without risking the QoS performance and call success rates is a major concern when it comes to wireless heterogeneous networks. In order to achieve this, a generic, fast and secure, Authentication and Key Agreement p...

Authentication and key agreement protocols play an important role in wireless sensor communication networks. Recently Xue et al’. suggested a key agreement protocols for WSN which in this paper we show that the protocol has some security flaws. Also we introduce an enhanced authentication and key agreement protocol for WSN satisfying all the security requirements.

Menezes–Qu–Vanstone key agreement (MQV) is intended to provide implicit key authentication (IKA) and several other security objectives. MQV is approved and specified in five standards. This report focuses on the IKA of two-pass MQV, without key confirmation. Arguably, implicit key authentication is the most essential security objective in authenticated key agreement. The report examines various...

Nalla and Reddy [6] presented new ID-based tripartite authenticated key agreement protocols from parings. Recently, Boneh and Silverberg [4] studied a one round multi-party key agreement protocols using the certificates from multilinear forms. In this paper, we propose new ID-based multi-party authenticated key agreement protocols, which use the identity information of a user as his long-term p...

Secure group communication is an active area of research and its popularity is fuelled by the growing importance of group-oriented applications such as teleconferences, collaborative workspace, pay per-view etc. A number of group key agreement protocols have been proposed for these objectives. However most of the protocols have not considers the anonymity of the participants. Although in some a...

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as refer...

We cryptanalyse a matrix-based key transport protocol due to Baumslag, Camps, Fine, Rosenberger and Xu from 2006. We also cryptanalyse two recently proposed matrix-based key agreement protocols, due to Habeeb, Kahrobaei and Shpilrain, and due to Romanczuk and Ustimenko.

Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. The EAP-SIM protocol was developed by 3GPP. The documentation of EAP-SIM is provided as information to the Internet community. While the EAP WG has verified that EAP-SIM is compatible with EAP, as defined in RFC 3748, no oth...
