A 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 کاملA 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 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 کاملScalable and fault-tolerant key agreement protocol for dynamic groups
With the widespread use of the Internet, the popularity of group communication-based applications has grown considerably. Since most communications over the Internet involve the traversal of insecure networks, basic security services are necessary for these collaborative applications. These security services can be facilitated if the authorized group members share a common secret. In such distr...
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...
