AMD was quick to upgrade the security of its processors from fTPM/TPM 2.0 to Microsoft’s Pluton with its Ryzen 6000 mobile processors. Pluton was launched by Microsoft in 2020 in partnership with AMD, Intel, and Qualcomm. It offers even better protection than a Trusted Platform Module (TPM or fTPM for firmware implementations) because it exists within the CPU, preventing attacks via the bus interface.
Intel, however, appears to be confident in its own TPM alternative, called Platform Trust Technology (PTT). The chipmaker is enhancing its Threat Detection Technology (TDT) on 12th Gen vPro CPUs through a partnership with ESET.
An Intel spokesperson has to The Register that “12th Gen platforms don’t support Pluton.” Furthermore, Lenovo has also confirmed that Pluton will not be enabled on 2022 ThinkPad models (including Ryzen 6000 devices). Thankfully, users will have the ability to enable it themselves.
