Transparent Proof-of-Work Mechanism for Protecting Web Applications from Attack
PSU researchers have developed a transparent, backwards compatible proof-of-work system -- a defense mechanism that allows server owners to give client-specific challenges to those requesting access to network resources. All clients are provided tasks to perform prior to access being granted, with easier & harder tasks available depending on t...
