We propose group communication as an efficient mechanism to support fault tolerance. Our approach is based on an efficient reliable broadcast protocol that requires on average onl...
The formidable difficulty in securing systems stems in large part from the increasing complexity of the systems we build but also the degree to which we now depend on information ...
Wireless sensor networks (WSN) are event based systems that rely on the collective effort of several microsensor nodes. Reliable event detection at the sink is based on collective...
We present an analysis of security vulnerabilities in the Domain Name System (DNS) and the DNS Security Extensions (DNSSEC). DNS data that is provided by name servers lacks suppor...
New technologies have recently emerged to challenge the very nature of computing: multicore processors, virtualized operating systems and networks, and data-center clouds. One can...
