Computation-Efficient Multicast Key Distribution

ABSTRACT:

Efficient key distribution is a crucial downside for secure group Communications. The Communication and storage complexity of multicast key distribution downside has been studied extensively. In this paper, we have a tendency to propose a new multicast key distribution theme whose computation complexity is significantly reduced. Instead of using standard encryption algorithms, the scheme employs MDS codes, a category of error control codes, to distribute multicast key dynamically. This scheme drastically reduces the computation load of every group member compared to existing schemes using traditional encryption algorithms. Such a theme is desirable for many wireless applications where moveable devices or sensors need to cut back their computation as a lot of as possible because of battery power limitations. Easily combined with any key-tree-based mostly schemes, this scheme provides abundant lower computation complexity whereas maintaining low and balanced Communication complexity and storage complexity for secure dynamic multicast key.
