What Is Intel TDX?

Intel Trust Domain Extensions (Intel TDX) is Intel's latest confidential computing technology, designed to protect sensitive data and applications within hardware-isolated virtual machines (VMs) known as Trust Domains (TDs). Intel TDX provides a hardware-based trusted execution environment (TEE) that isolates TDs from the Virtual Machine Manager (VMM), the hypervisor, and other non-TD software on the host platform. This isolation is achieved through hardware extensions that manage and encrypt memory, ensuring both confidentiality and integrity of the TD's CPU state. It provides protection from untrusted BIOS, the hypervisor, device drivers, and cloud management software. By ensuring data integrity, confidentiality, and authenticity, Intel TDX enhances trust in virtualised environments, making it a robust solution for securing critical data processing tasks.
