— Both broadcast encryption (BE) protocols and multicast key distribution (MKD) protocols try to solve the same problem of private group communication. For the first time, we dis...
Efficient key distribution is an important problem for secure group communications. The communication and storage complexity of multicast key distribution problem has been studied ...
For an efficient role based access control using attribute certificate in highly distributed computing environments, we use a technique of structuring role specification certificat...
—Multicasting has not been widely adopted until now, due to lack of access control over the group members. The Authentication, Authorization and Accounting (AAA) protocols are be...
In wireless networks, secure multicast protocols are more difficult to implement efficiently due to the dynamic nature of the multicast group and the scarcity of bandwidth at the ...
