Trapdoors for Hard Lattices and New Cryptographic Constructions
We show how to construct a variety of “trapdoor” cryptographic tools assuming the worst-case hardness of standard lattice problems (such as approximating the length of the sho...

Constructing basis functions from directed graphs for value function approximation
Basis functions derived from an undirected graph connecting nearby samples from a Markov decision process (MDP) have proven useful for approximating value functions. The success o...

Optimal buffered routing path constructions for single and multiple clock domain systems
Shrinking process geometries and the increasing use of IP components in SoC designs give rise to new problems in routing and buffer insertion. A particular concern is that cross-c...
