Cryptanalysis of Al-Riyami-Paterson's Authenticated Three Party Key Agreement Protocols

Authenticated Three Party Key Agreement Protocols from Pairings

Multi-party authenticated key agreement protocols from multi-linear forms

Joux [10] presented a one round protocol for tripartitie key agreement and Al-Riyami et.al. [15] developed a number of tripartitie, one round, authenticated protocols related to MTI and MQV protocols. Recently, Boneh and Silverleg [4] studied multilinear forms, which provides a one round multi-party key agreement protocol. In this paper, we propose (n + 1) types of one round authenticated multi...

Tripartite Authenticated Key Agreement Protocols from Pairings

Joux’s protocol [29] is a one round, tripartite key agreement protocol that is more bandwidth-efficient than any previous three-party key agreement protocol. But it is insecure, suffering from a simple man-inthe-middle attack. This paper shows how to make Joux’s protocol secure, presenting several tripartite, authenticated key agreement protocols that still require only one round of communicati...

Cryptanalysis and improvement of two certificateless three-party authenticated key agreement protocols

Recently, two certificateless three-party authenticated key agreement protocols were proposed, and both protocols were claimed they can meet the desirable security properties including forward security, key compromise impersonation resistance and so on. Through cryptanalysis, we show that one neither meets forward security and key compromise impersonation resistance nor resists an attack by an ...

Analysis of Two Pairing - based Three - party Password

Password-Authenticated Key Exchange (PAKE) protocols allow parties to share secret keys in an authentic manner based on an easily memorizable password. Recently, Nam et al. showed that a provably secure three-party passwordbased authenticated key exchange protocol using Weil pairing by Wen et al. is vulnerable to a man-in-the-middle attack. In doing so, Nam et al. showed the flaws in the proof ...
