A Scalable Extension of Group Key Management Protocol
This paper presents a robust, scalable extension to the recently proposed multicast Group Key Management Protocol (GKMP) ([1], [2]), in terms of security administration. The GKMP has two major security related problems, (a) lack of any mechanism to remove a compromised group administrator, (b) lack of scalability. We are able to remove a compromised single panel member from generating the group...
متن کاملA Scalable and Adaptive Key Management Protocol for Group Communication
Multicasting is increasingly used as an efficient communication mechanism for group-oriented applications in the Internet. In order to offer secrecy for multicast applications, the traffic encryption key has to be changed whenever a user joins or leaves the system. Such a change has to be communicated to all the current group members. The bandwidth used for such rekeying operation could be high...
متن کاملSimulation of A Novel Scalable Group Key Management Protocol for Mobile Adhoc Networks
A Mobile Adhoc Network (MANET) is a collection of autonomous nodes that communicate with each other ,most frequently using a multi-hop wireless network. Secure and multicast group communication is an active area of research in MANETS. The main problem in secure group communication is group dynamics and key management. Group key management is crucial for multicast security. Member joining and me...
متن کاملA novel Group Key Transfer Protocol
Group key transfer protocols depend on a mutually trusted key generation center (KGC) to transport the group key to all group members secretly. This approach requires that a trusted sever be set up, and it incurs communication overhead costs. In addition, the existing group key transfer protocols based on secret sharing all use threshold schemes that need to compute a -degree interpolating poly...
متن کاملScalable Delay-constrained Multicast Group Key Management
In the last few years, multicasting is increasingly used as an efficient communication mechanism for group-oriented applications in the Internet. Some multicast applications require confidentiality for transmitted data. So, a traffic encryption key is used to assure this confidentiality and has to be changed and distributed to all valid members whenever a membership change (join or leave) occur...
