DESCRIPTION:Confidential VMs enable cloud service providers to operate a se
 cure and trustworthy multi-tenant cloud infrastructure.\nWhile confidentia
 l VMs ensure comprehensive protection for cloud workloads\, such heavy-wei
 ght isolation is often omitted for serverless applications that co-locate 
 thousands of cloud workers within the same process to optimize FaaS overhe
 ads through efficient context switches.\nIn this work\, we present CAGE-V\
 , a novel confidential computing architecture that supports lightweight en
 clave-based isolation for individual cloud workers running inside confiden
 tial VMs.\nGuest enclaves support fast context switches within the confide
 ntial VM\, as TLB entries are tagged with Domain Identifiers\, eliminating
  overheads that stem from TLB flushes.\nWe present a CAGE-V prototype\, co
 nsisting of a hardware extension for the CORE-V CVA6 processor and a small
  security monitor\, and evaluate our design in terms of system performance
 \, demonstrating a minor performance impact.
