Optimal randomized algorithms for multipacket and cut through routing on the mesh
In this paper, we present a randomized algorithm for the multipacket (i.e., k − k) routing problem on an n × n mesh. The algorithm completes with high probability in at the mos...

Bounded-Concurrent Secure Two-Party Computation in a Constant Number of Rounds
We consider the problem of constructing a general protocol for secure two-party computation in a way that preserves security under concurrent composition. In our treatment, we foc...

Correcting limited-magnitude errors in the rank-modulation scheme
We study error-correcting codes for permutations under the infinity norm, motivated the rank-modulation scheme for flash memories. In this scheme, a set of n flash cells are combin...
