Abstract--Wireless sensor networks have received a lot of attention recently due to its wide applications. An accurate and synchronized clock time is crucial in many sensor network...
Modern operating systems primarily use Discretionary Access Control (DAC) to protect files and other operating system resources. DAC mechanisms are more user-friendly than Mandat...
Cache attacks on implementations of cryptographic algorithms have turned out to be very powerful. Progress in processor design, e.g., like hyperthreading, requires to adapt models ...
: e-business organizations are heavily dependent on distributed 24X7 robust information computing systems, for their daily operations. To secure distributed online transactions, th...
In a recent work, we have shown that it is not possible to dependably build any type of distributed f fault or intrusiontolerant system under the asynchronous model. This result f...
