Abstract [en]

Denial of Service (DoS) aims to drain the underlying resources

of a service and is a increasing problem for today’s

service providers. In this paper, we propose a novel reputation

based proof-of-work (RB-PoW) protocol based on

adaptive scaling of puzzle difficulties to mitigate various

denial-of-service attacks. A testing framework was developed

to examine RB-PoW’s effectiveness against classical

PoW protocols in simulated DoS attacks. We concluded

that in flooding type of denial-of-service attacks the RBPoW

model is superior to the classical PoW that is based

solely on server load. Both offer similar performance when

exposed to drain-type denial-of-service attacks.
