On the security of an identity-based authenticated group key agreement protocol for imbalanced mobile networks
نویسنده
چکیده
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.

Security 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.

Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...
متن کاملA secure authenticated group key agreement protocol for resource-limited mobile devices
With rapid growth of mobile wireless networks, many mobile applications have received significant attention. However, security will be an important factor for their full adoption. Most security technologies currently deployed in wired networks are not fully applicable to wireless networks involved in resource-limited mobile nodes because of their low-power computing capability and limited energ...
متن کاملA TESLA-based mutual authentication protocol for GSM networks
The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...
