Abstract

We provides an evaluation of non-parallelizable puzzles used to prevent DoS in authentication protocols. With an evaluation based on a simulation and performance analysis, this approach helps a responder to resist against DoS, as well as improves the throughput of services for legitimate clients. Another key strength is that the construction and verification at the responder is simple and fast.
