 is the Community Manager of Profian and the Enarx project\,\n   which is p

 . Previously\, he was the Director of Community and Business\n   Developme

 ware and machine learning research\, and\n   publishing several papers\, R
 ichard decided to switch gears and work on\n   Enarx and Confidential Comp
 uting. He is also a part-time computer\n   science instructor at a univers

 st and contributor to several open source projects\,\n   including the Ena
 rx project.\n\n   Description:\n   Wordle is a popular web-based game\, wh
 ere a single player has to guess\n   a five-letter word in six attempts\, 
 with yellow/green colored titles\n   shown as hints in each round\, indica
 ting letters that match with the\n   secret word.\n\n   We’ve created an
  open source clone of Wordle called Cryptle\, with\n   the goal of demonst
 rating data encryption in use\, where the processing\n   of the data is do
 ne in a Trusted Execution Environment (TEE)\, and only\n   accessible to t
 he Cryptle application.\n\n   Cryptle is similar to Wordle but one importa
 nt difference is that it\n   is multi-party and the secret words are sugge
 sted by the players\n   themselves. Each player proposes words that are mo
 st likely to match\n   those sent by others. The words are sent to the Cry
 ptle application\n   deployed and running in an Enarx Keep (a specific TEE
  instance) and\n   are only revealed to the players when there’s a match
  between the\n   secret words.\n\n   The standard way to engage with the g
 ame is for players to guess the\n   secret words by playing Cryptle from t
 he client side. However\, we will\n   also be allowing an alternative: pla
 yers may write an open source\n   application which runs with root privile
 ges on the host side and\n   attempts to derive or otherwise guess the sec
 ret words. Since Cryptle\n   makes use of Confidential Computing\, players
  shouldn't be able to read\n   what's in memory\, even with root access.\n
 \n   We'll provide an overview of an exploit of Enarx and we'll explain ho
 w\n   we were able to fix it. Attendees will be invited to find new\n   vu
 lnerabilities as part of the Cryptle Hack Challenge.\n\n   '\n\n   1. http
