What is TDX Intel?
Intel Trust Domain Extensions (TDX) is an architectural extension that provides TEE capabilities in the 4th Generation Intel Xeon Scalable Processors. TDX introduces the SEAM to offer cryptographic isolation and protection for Virtual Machines (VMs), which are called Trust Domains (TDs) in the TDX terminology.
Is Intel SGX discontinued?
A pivot by Intel in 2021 resulted in the deprecation of SGX from the 11th and 12th generation Intel Core processors, but development continues on Intel Xeon for cloud and enterprise use.
What is TDX?
