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 ...
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.

Infineon also developed additional software that can be used in conjunction with DAVE for specific microcontroller families or additional hardware: DAVE Bench for XC800 is a platform providing free development tools for Infineon's 8-bit microcontroller family, based on the Open Source Eclipse architecture.

Infineon announced in June 2019 that it would acquire Cypress Semiconductors for US$9.4 billion. [33] [34] The acquisition closed on 17 April [35] of 2020. [36] In May 2023, Infineon acquired "tiny machine learning" company Imagimob, a Stockholm, Sweden–based company with a platform for development and deployment of AI applications. [37]
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.
The platform uses up to 2 cores in TriCore lockstep mode, a lockstep architecture combined with safety technology such as internal communication buses or distributed memory protection systems. Hardware level encapsulation techniques allow integration of software with various safety levels (QM to ASIL-D) from different sources, reducing the ...
