Abstract:A (computational) client puzzle scheme enables a client to prove to a server that a certain amount of computing resources (CPU cycles and/or Memory look-ups) has been dedicated to solve a puzzle. In a number of different scenarios, researchers have applied client puzzle schemes to mitigate DoS attacks. In this paper, we introduce two batch verification modes for the RSW client puzzle scheme in order to improve the verification efficiency for the server, and investigate three methods for handling incorrect solutions in batch verifications.
