We prove that if NP ⊆ BPP, i.e., if SAT is worst-case hard, then for every probabilistic polynomial-time algorithm trying to decide SAT, there exists some polynomially samplable ...
All-optical packet switching (AOPS) technology is essential to fully utilize the tremendous bandwidth provided by advanced optical communication techniques through forwarding pack...
Grids are intended to enable cross-organizational interactions which makes Grid security a challenging and nontrivial issue. In Grids, delegation is a key facility that can be used...
