Decision Tree Based Key Management for Secure Group Communication

Bit Model Based Key Management Scheme for Secure Group Communication

For the last decade, researchers have started to focus their interest on Multicast Group Key Management Framework. The central research challenge is secure and efficient group key distribution. The present paper is based on the Bit model based Secure Multicast Group key distribution scheme using the most popular absolute encoder output type code named Gray Code. The focus is of two folds. The f...

Hierarchical based group key transfer for secure group communication

In this research paper, a scalable and efficient multicast secure protocol for large and dynamic systems that relies on trusted Key Generation Center (KGC) is proposed. In this protocol, we partition the entire group into several subgroups which is controlled by Intermediate Controller (IC). Our protocol is based on Iolus protocol and the hierarchical structure of LKH protocol. The decompositio...

EÆcient Collaborative Key Management Protocols for Secure Autonomous Group Communication

This paper introduces a new family of protocols addressing collaborative group key agreement for secure group communication in autonomous groups. I present three protocols with varying degrees of security and efciency. The rst protocol provides a non-authenticated key agreement and is suitable for applications with low security requirements. The second and third protocols add a DiÆe-Hellman-bas...

Key Management for Secure Multicast Group Communication in Mobile Networks

—This paper describes the implementation of a hierarchical key management system to provide secure multicast communications in mobile network environments. By using this hierarchical system, both efficiency and security are improved and a highly scalable system is created.
