Novel Multicast Key Authentication Protocol

Efficient key distribution is an important problem for secure group communications in wireless networks. The Authentication is a vital requirement process in order to prevent intruders attack  prior to the key distribution and exchange process in  multicast key distribution. In this paper, we propose a new multicast key Authentication key transfer protocol based on MDS scheme that ensures secure distributed Standard authentication scheme. Instead of using conventional encryption algorithms, the scheme employs MDS codes, a class of error control codes, to distribute multicast key dynamically. This scheme drastically reduces the Authentication load of each group member compared to existing schemes employing traditional encryption algorithms. Such a scheme is desirable for many wireless applications where portable devices or sensors need to reduce their Authentication as much as possible due to battery power limitations. Easily combined with PFMH key-tree-based schemes, this scheme provides much lower Authentication complexity while maintaining low and balanced communication complexity and storage complexity for secure dynamic multicast key distribution.
