Research Interests

My major areas of interest are secure networking and reliability for distributed systems. For my Ph.D. thesis, I am currently working three problems. I am working on the design of secure multicast routing protocols for hybrid terrestrial/satellite networks. I am also investigating key management techniques for secure multicast data transmission for the hybrid network architectures. Lastly, I am looking at the requirements for reliability in group communication in hybrid networks, and investigating efficient approaches for the same.
