Secret Key Amplification from Uniformly Leaked Key Exchange Complete Graph,ependently with a fixed probability . (and, thus, is perfectly secure with a probability of .). Using these pre-shared, possibly leaked keys, we want two designated players to share a common one-bit secret key in cooperation with other players so that Eve’s knowledge about the generated secret key w

Two New Schemes in the Bitprobe Model,e literature. One such scheme is to store three elements using two queries in the adaptive bitprobe model. Previously, the maximum number of elements that can be handled using two queries in the adaptive model is two, which is due to Radhakrishnan . [.]. A corollary of this result is an explicit sch

Faster Network Algorithms Based on Graph Decomposition,ata structures) from a given graph, then use them for solving the problems. A basic problem is an all pairs maximum flow problem, which consists of two stages. In a preprocessing stage we construct an index, and in a query stage we process the query using the index. We can solve all pairs maximum fl
