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...
متن کاملProvable password-based tripartite key agreement protocol
A password-based tripartite key agreement protocol is presented in this paper. The three entities involved in this protocol can negotiate a common session key via a shared password over insecure networks. Proofs are given to show that the proposed protocol is secure against forging and chosen message attacks in the case of without actually running a dictionary attack.
متن کاملID-based tripartite Authenticated Key Agreement Protocols from pairings
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...
متن کاملCryptanalysis of ID-based Tripartite Authenticated Key Agreement Protocols
In this paper, we show that the Nalla-Reddy’s one round IDbased tripartite authenticated key agreement protocols are still insecure against the man-in-the-middle attacks. We also break the Nalla’s IDbased tripartite authenticated key agreement protocol with signatures.
متن کاملComparative Study of Tripartite Identity-Based Authenticated Key Agreement Protocols
Key agreement protocols are used to exchange keys between two or multiple entities. The exchanged key can be later used to assure confidentiality through encryption. Additionally authenticated key agreement protocols offer implicit authentication. In this paper we conduct a security and efficiency comparison of tripartite authenticated identity-based key agreement protocols and review all of th...
