Field upgrade is the TCG term for updating the TPM firmware. The update can be between TPM 1.2 and TPM 2.0, or between firmware versions. Some vendors limit the number of transitions between 1.2 and 2.0, and some restrict rollback to previous versions. [citation needed] Platform OEMs such as HP [85] supply an upgrade tool.
The vulnerability arises from an approach to RSA key generation used in vulnerable versions of the software library RSALib provided by Infineon Technologies and incorporated into many smart cards, Trusted Platform Modules (TPM), and Hardware Security Modules (HSM), including YubiKey 4 tokens when used to generate RSA keys on-chip for OpenPGP or ...
Intel Platform Trust Technology (PTT), a firmware-based Trusted Platform Module (TPM) [27] [33] Near Field Communication, a middleware for NFC readers and vendors to access NFC cards and provide secure element access, found in later MEI versions. [34]
The flaw is the Return of Coppersmith's Attack or ROCA vulnerability which is in a code library developed by Infineon and had been in widespread use in security products such as smartcards and TPMs. Microsoft released an updated version of the firmware for Infineon TPM chips that fixes the flaw via Windows Update.

Trusted Platform Module, a specification for a secure cryptoprocessor included with some computers; Tivoli Provisioning Manager, a software product by IBM; Trade promotion management, software that supports the management of trade promotion; Technical protection measures, another name for digital rights management
Furthermore, the TPM has the capability to digitally sign the PCR values (i.e., a PCR Quote) so that any entity can verify that the measurements come from, and are protected by, a TPM, thus enabling Remote Attestation to detect tampering, corruption, and malicious software.
Using a standardized interface and protocol allows systems-management software based on IPMI to manage multiple, disparate servers. As a message-based, hardware-level interface specification, IPMI operates independently of the operating system (OS) to allow administrators to manage a system remotely in the absence of an operating system or of the system management software.
The Intel Classmate PC (a competitor to the One Laptop Per Child) includes a Trusted Platform Module. [53] PrivateCore vCage software can be used to attest x86 servers with TPM chips. Mobile T6 secure operating system simulates the TPM functionality in mobile devices using the ARM TrustZone technology. [54]
