Building Blocks of Confidential Computing

The software ecosystem for Confidential Computing is quickly evolving. With the availability of hardware and adoption of hyperscalers the technology also becomes more accessible to end users. In this talk I will look at the building blocks of virtualization-based Confidential Computing environments, starting at the hardware level, explaining the hypervisor and operating system support, up to integrity measured boot and user-space. I will also cover what is currently supported in Linux and the ongoing work.
