A secure key agreement protocol for dynamic group

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC

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 ...

Secure Group Key Agreement

Secure group key agreement

As a result of the increased popularity of group-oriented applications and protocols, group communication occurs in many different settings: from network multicasting to application layer teleand video-conferencing. Regardless of the application environment, security services are necessary to provide communication privacy and integrity. This thesis considers the problem of key management in a s...

Secure authenticated group key agreement protocol in the MANET environment

Due to dynamic and infrastructure-less nature of Mobile Ad hoc Network (MANET) environment, there exist number of threats as mobile devices and nodes could freely move around in MANET such as eavesdropping of communications channels, modification of sensitive m-commerce transactions, Denial of Service(DoS), vulnerabilities of impersonation by malicious insiders etc. In this paper, we propose a ...

Secure key agreement for group communications

-Many key establishment protocols have been proposed for secure group communications. However, these protocols share the limitations that group members are not mutually authenticated, dynamic group membership is not considered, and the cost of key establishment is substantial. A secure key agreement protocol for group communications is proposed in this paper, which ensures the authenticity of g...
