ID-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 کاملTripartite 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 کاملCryptanalysis of Two ID-based Authenticated Key Agreement Protocols from Pairings
Recently, a number of ID-based two-party authenticated key agreement protocols which make of bilinear pairings have been proposed [3, 8, 12, 11, 14]. In this paper, we show that the Xie’s protocol [14] does not provide implicit key authentication and key-compromise impersonation resilience. Also, we point out the vulnerability of the Choi et al’s protocol [3] against signature forgery attacks.
متن کاملCryptanalysis on Identity-based Authenticated Key Agreement Protocols from Pairings
Two-party authenticated key agreement protocol is used to authenticate entities and establish session keys in an open network in order to provide secure communications between two parties. Several security attributes are highly desired for such protocols, such as perfect forward secrecy (the corruption of long-term keys of all the entities should not compromise any session key), PKG forward sec...
متن کاملA new two-round certificateless authenticated key agreement protocol without bilinear pairings
Certificateless public key cryptography (CLPKC), which can simplify the complex certificate management in the traditional public key cryptography and resolve the key escrow problem in identity-based cryptography, has been widely studied. As an important part of CLPKC, certificateless two-party authenticated key agreement (CTAKA) protocols have also received considerable attention. Recently, man...
