The crypto group (CLUB) of Computer Science Department, Università degli Studi di Milano, in collaboration with De Componendis Cifris (Associazione italiana di Crittografia) and Clusit (The Italian Association for Computer Security), organizes the "Cryptowars 2020". The event is organized within the framework of the ECSM (European Cyber Security Month) and targets students. This contest aims to raise awareness of the fact that cryptographic algorithms get old and they should be continuously tested, maintained, improved (which is what cryptographers - among other things - do).
