Secure Key Agreement And Authentication Protocols

Authentication and Key Agreement Protocols Preserving Anonymity

Anonymity is a very important security feature in addition to authentication and key agreement features in communication protocols. In this paper, we propose two authentication and key agreement (AKA) protocols: the AKA protocol with user anonymity (UAP) and the AKA protocol with user and server anonymity (USAP). The proposed protocols have the following advantages: first of all, they preserve ...

The Provably Secure Formal Methods for Authentication and Key Agreement Protocols

In the design and analysis of authentication and key agreement protocols, provably secure formal methods play a very important role, among which the Canetti-Krawczyk (CK) model and universal composable (UC) security model are very popular at present. This chapter focuses on these two models and consists mainly of three parts: (1) an introduction to CK model and UC models; (2) A study of these t...

SAS-Based Group Authentication and Key Agreement Protocols

New trends in consumer electronics have created a strong demand for fast, reliable and user-friendly key agreement protocols. However, many key agreement protocols are secure only against passive attacks. Therefore, message authentication is often unavoidable in order to achieve security against active adversaries. Pasini and Vaudenay were the first to propose a new compelling methodology for m...

Provably-Secure Enhancement on 3GPP Authentication and Key Agreement Protocol

Key agreement protocols for distributed secure multicast over the ring

Protocols for authenticated key exchange allow parties within an insecure network to establish a common session key which can then be used to secure their future communication. In this paper we introduce a protocol for distributed key agreement over a noncommutative ring with a large number of noninvertible elements. This protocol uses polynomials with coefficients in the center of the ring. We...
