DESCRIPTION:Neelu Shivprakash Kalani\nEDIC candidacy exam\nExam president:
  Prof. Babak Falsafi\nThesis advisor: Prof. Edouard Bugnion\nCo-examiner: 
 Prof. Mathias Payer\n\nAbstract\nContinuously emerging applications of Tru
 sted Execution Environments (TEEs) starting from cloud services to embedde
 d devices have led to growth in this research area. Existing TEE designs v
 ary in numerous aspects such as their adaptability for use-cases\, develop
 ment costs\, feature support\, etc. Among these designs\, we pick and desc
 ribe three different approaches of building TEEs that provide similar isol
 ation guarantees by leveraging different system characteristics in softwar
 e (e.g. virtualization) or hardware (e.g. security primitives)\, and provi
 de varying magnitudes of flexibility in their designs. We compare and cont
 rast these designs over a set of desirable TEE characteristics\, and extra
 ct several limitations that still need to be addressed for creating optima
 l TEEs. Building on these insights\, we present our proposal to improve ov
 er existing TEE designs by minimizing trust and improving modularity in TE
 E architectures.\n\nBackground papers\n1) Overshadow: A Virtualization-Bas
