The National Science Foundation (Cybertrust program) has awarded Tom Shrimpton and Wu-chang Feng $400,000 to investigate the use of network-level 'puzzles', cryptographic or combinatorial tasks of varying difficulties, in order to thwart denial-of-service attacks. "Making Proofs-of-Work Work" is a three-year grant with the dual objectives of giving the puzzle-problem a theoretical treatment (giving it proper syntax, security definitions, and building provably-secure constructions), and of addressing design and implementation issues associated with deploying puzzles at the network layer.
