Batch rekeying has been used for improving the group rekeying efficiency in a large-scale
group communication. However, there exists a tradeoff between the number of rekeying …

Multicast security is becoming an important networking issue because of the growing
number of network applications that rely on multicast communication. Scalable group re …

A group key management has an important role in multicast security in order to achieve data
integrity and confidentiality. The session key is a common secret key for a group of users in …

Storage, delivery and update of cryptographic keys are the most important items to study in
multicast security. Traditionally a centralized trusted third party called the key server (KS) …

There are several group key management solutions to implement group rekeying in secure
multicast communication. These solutions suffer from 1 affects all phenomena if they use …

For a long time multicast security researches have been going on. In multicast security the
group key must be changed whenever users join or leave. We called it'rekeying'. There are …

Group multicast is becoming a prevalent issue in network applications such as
teleconferencing, pay-per-view, and information services. In order to secure group …

Scalable group rekeying schemes proposed in the literature can be classified into two
categories: stateful schemes, eg, logical key hierarchy (LKH) based approaches, and …

Many network applications based on a group communications model have been developed.
As a remit securing group communications, ie, providing confidentiality, authenticity and …

We investigate optimal rekeying interval problem in batch rekeying. A Markov model is
developed for batch rekeying process. The model is then used to analyze the relationship …
