DESCRIPTION:Christian Mouchet\nEDIC candidacy exam\nExam president: Prof. 
 Carmela Troncoso\nThesis advisor: Prof. Jean-Pierre Hubaux\nCo-examiner: P
 rof. Bryan Ford\n\nAbstract\nThe concept of cloud computing typically refe
 rs to a computation environment that is logically and physically owned by 
 different entities. Such separation of concerns allows for convenient cent
 ralization of hardware resources\, which facilitates maintenance and amort
 izes costs. Unfortunately\, this also raises concerns about potential priv
 acy violations such as abuse or leakage of sensitive data by the providers
  of these services.\n \nThis work discusses the role cryptography in priv
 acy-preserving cloud computing. First\, by presenting a hierarchical class
 ification of such systems based on the notion of cryptographically defined
  trust boundaries. Then\, two concrete systems are analyzed and positioned
  within this theoretical context. An important result is presented\, stati
 ng that the most general class\, in which input data is distributed betwee
 n multiple distrusting clients\, cannot be realized by any 2-party cryptog
 raphic scheme. Finally\, promising research directions acknowledging this 
 impossibility result are proposed.\n \n \nBackground papers\nOn the Impo
