SUMMARY:Building trustworthy multi-party systems in the cloud (without han
 dling over the keys to the kingdom)  - Heidi Howard\, Microsoft Research

DESCRIPTION:In the pre-cloud era\, computer systems were operated directly
  by the organizations which depended upon them. This approach\, that later
  became known as on-premises\, gave organizations great power over their s
 ystems\, for instance\, the ability to control who had access to their dat
 a. However\, “with great power comes great responsibility” and organiz
 ations were left with the ongoing burden of deploying and managing their o
 wn systems. Then along came cloud computing\, which promised to free organ
 izations of this burden and the mass migration to the cloud began. Cloud c
 omputing today has removed much of the responsibility of deploying systems
 \, however\, it has also removed much of the power that organizations once
  had. Organizations must place their trust in the cloud to maintain the co
 nfidentiality of their data and the integrity of their code. \n\nIn this t
 alk\, I will consider whether it is possible to regain control over system
 s in the cloud (all of the power with none of the responsibility) and even
  enable multiple untrusted parties to compute together in the cloud. Do no
 t fear\, this is not a web3 or cryptocurrency talk 😛. Instead\, we will
  look at TEEs (Trusted Execution Environments) and the emerging ecosystem 
 of software around them. I will introduce CCF (Confidential Consortium Fra
 mework)\, an open-source framework for building a new category of secure\,
  highly available\, and confidential applications that focus on multi-part
 y compute in the cloud. By the end of the talk\, I hope to have convinced 
 you that distributing systems does not necessarily mean distributing trust
  in the era of trusted execution in the cloud.
