چکیده
Recently, Isalam and Biswas proposed a new group key agreement (GKA) protocol for imbalanced mobile networks. In this letter, we will show that Isalam et al.’s GKA protocol is not secure.

On the security of an identity-based authenticated group key agreement protocol for imbalanced mobile networks
Recently, Islam and Biswas proposed a pairing-free identity-based authenticated group key agreement protocol for imbalanced mobile networks. However, in this letter, we point out that this protocol cannot resist passive attack, and cannot provide forward secrecy for joining operation and backward secrecy for leaving operation.
متن کاملSecurity Analysis of a Pairing-free Identity-based Authenticated Group Key Agreement Protocol for Imbalanced Mobile Networks
Recently, Isalam and Biswas proposed a new group key agreement (GKA) protocol for imbalanced mobile networks. In this letter, we will first prove that Isalam and Biswas’s GKA protocol cannot provide perfect forward secrecy. Then we will point out that their GKA protocol is vulnerable to ephemeral key compromise attack.
متن کاملCryptanalysis of pairing-free certificateless authenticated key agreement protocol
Abstract: Recently, He et al. [D. He, J. Chen, J. Hu, A pairing-free certificateless authenticated key agreement protocol, International Journal of Communication Systems, 25(2), pp. 221-230, 2012] proposed a pairing-free certificateless authenticated key agreement protocol and demonstrated that their protocol is provable security in the random oracle model. However, in this paper, we show that ...
متن کاملA Pairing-Free Identity-Based Authenticated Key Agreement Protocol for MANET
Providing a suitable authenticated key establishment protocol in MANETs is challenging due to all the characteristics of networks, such as communication capability, computation capability and storage resources. This paper presents an efficient and flexible authenticated key agreement protocol without bilinear pairings for MANET. Our proposed protocol not only provides mutual authentication betw...
متن کاملAn efficient certificateless two-party authenticated key agreement protocol
Due to avoiding the key escrow problem in the identity-based cryptosystem, certificateless public key cryptosystem (CLPKC) has received a significant attention. As an important part of the CLPKC, the certificateless authenticated key agreement (CLAKA) protocol also received considerable attention. Most CLAKA protocols are built from bilinear mappings on elliptic curves which need costly operati...
