virtCCA: Virtualized Arm Confidential Compute Architecture with TrustZone

arXiv:2306.11011v2 Announce Type: replace
Abstract: ARM recently introduced the Confidential Compute Architecture (CCA) as part of the upcoming ARMv9-A architecture. CCA enables the support of confidential virtual machines (cVMs) within a separate world called the Realm world, providing protection from the untrusted normal world. While CCA offers a promising future for confidential computing, the widespread availability of CCA hardware is not expected in the near future, according to ARM's roadmap. To address this gap, we present virtCCA, an architecture that …
