DESCRIPTION:Hardware-assisted trusted execution environments (TEEs) are cr
 itical building blocks of many modern applications. However\, they have a 
 one-way isolation model that introduces a semantic gap between a TEE and i
 ts outside world. This lack of information causes an ever-increasing set o
 f attacks on TEE-enabled applications that exploit various insecure intera
 ctions with the host OSs\, applications\, or other enclaves. In this talk\
 , I will introduce Sirius\, the first compartmentalization framework that 
 achieves strong isolation and secure sharing in TEE-assisted applications 
 by controlling the dataflows within primary kernel objects (e.g. threads\,
  processes\, address spaces\, files\, sockets\, pipes) in both the secure 
 and normal worlds. Sirius replaces ad-hoc interactions in current TEE syst
 ems with a principled approach that adds strong intra-address space isolat
 ion and effectively eliminates a wide range of attacks. \n\nBio: Zahra is 
 PhD student in the Systems Research Group at the Cambridge University Comp
 uter Laboratory. Her research interest is operating systems\, security\, v
 irtualization\, and trustworthy computing. In particular\, her work is cen
 tered around building systems to provide applications with strong isolatio
 n and fine-grained compartmentalization mechanisms. \nShe did several rese
 arch internships at Microsoft Research Redmond and Cambridge and received 
 her MS degree from Indiana University Bloomington.
