Cryptanalysis of an ID-based Authenticated Dynamic Group Key Agreement with Optimal Round
نویسندگان
چکیده
Recently, Teng, Wu and Tang proposed a new ID-based authenticated dynamic group key agreement (DGKA) protocol. They claimed that leaving users cannot calculate subsequent group session keys and joining users cannot calculate previous group session keys. In this paper, we will show that Teng et al.’s protocol cannot provide forward confidentiality or backward confidentiality.

Cryptanalysis 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 کاملImpossible Differential Cryptanalysis on Deoxys-BC-256
Deoxys is a final-round candidate of the CAESAR competition. Deoxys is built upon an internal tweakable block cipher Deoxys-BC, where in addition to the plaintext and key, it takes an extra non-secret input called a tweak. This paper presents the first impossible differential cryptanalysis of Deoxys-BC-256 which is used in Deoxys as an internal tweakable block cipher. First, we find a 4.5-round...

Xinjun Du, Ying Wang, Jianhua Ge and Yumin Wang Key Laboratory of Computer Networks and Information Security Xidian University Xi’an 710071, P.R. China Abstract: This paper proposes an ID-based authenticated two round multi-party key agreement among n parties. Several ID-based two-party and tripartite key agreement schemes were proposed recently. Rana Barua attempted to extend Joux’s tripartite...
متن کاملPerfect Forward Secure ID-based Key Agreement Protocol in Group Communication
Several identity-based key agreement protocols using bilinear pairing have been proposed in recent years and none of them has achieved all required security properties. In this paper, we firstly propose an ID-based one round authenticated group key agreement protocol with bilinear pairings, where all participants can generate the group session key in one round. Based on the intractability of el...
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.
