The standardized Authentication and Key Agreement protocol for 5G networks (5G AKA) have several security privacy vulnerabilities. In this paper, we propose a novel authentication key agreement beyond that is compatible with the AKA. Our has properties, e.g., perfect forward secrecy, resistance against linkability attacks, protection malicious SNs. Moreover, both user identity secrecy are handl...

This paper proposes ID-based tripartite authenticated key agreement protocols. The authenticated three party key agreement protocols from pairings [15], and the ID-based two party authenticated key agreement protocol [13] are studied. These two protocols are taken as the basis for designing three new ID-based tripartite authenticated key agreement protocols. The security properties of all these...

Recently, Cheng et al. proposed two tripartite key agreement protocols from pairings: one is certificate-based and the other is identity-based (ID-based). In this article, we show that the two schemes are vulnerable to the insider impersonation attack and the ID-based scheme even discloses the entities’ private keys. Solutions to this problem are discussed.
