For steps on how to switch PCR banks on TPM 2.+ * Below code implements the procedure defined in TCG EFI Protocol + * Specification Family "2. New hierarchies separate the authorization of different usage levels and improve the management of objects. The PCR spec is documented in in the section "PCR bank specifiers". TPM is not available, TPM is not usable.The PCR 0- 7 banks have well defined Posted: (5 days ago) 1 The Trusted Platform Module The TPM is a security specification defined by the Trusted Computing Group. PCRs (Set of registers) are a key ingredient of the TPM. 0, TPMs no longer hard-code the SHA-1 algorithm for PCRs. PCR banks: So, effectively a PCR bank would be a way to group PCRs together logically but they could use the same underlying PCRs. tpm: replace TPM algorithms IDs with tpm_pcr_bank_info structs in tpm_chip Message ID 20170621142941.The PCR’s are primarily used to cryptographically measure the software and hardware state when booting the device. Their prime use case is to provide a method to cryptographically record (measure) software state: both the software running on a platform and configuration data used by that software. Support for TPM SHA384 PCR banks has been added.

0 devices on your PC, you should contact your OEM or UEFI vendor Update your security processor (TPM) firmware Within each TPMS_PCR_SELECTION, the TPM will process the bits in the pcrSelect array in ascending PCR order (see ISO/IEC 11889-2 for definition of the PCR order). 0" to parse the event log in Crypto Agile + * Log Entry Format. This includes support for the BIOS/EFI event log and variable sized PCR banks. To decode a log, run the following command: Console. Below code implements this procedure to parse SHA1 The struct is: typedef struct TPML_PCR_SELECTION As far as I understand this is going to change with a new revision and TPM2_NUM_PCR_BANKS will be 16 since newer hardware supports more PCR banks. + * This is called Crypto Agile Log Entry Format. 2 TPM is much easier by comparison since only the fixed width SHA1 hash is supported. One can use either the -g or -L mutually exclusive options to filter the output. This topic provides background about what happens when you switch pcr banks on tpm 2.0 devices on your pc, you should contact your oem or uefi vendor. But by weaponizing this flaw, attackers can corrupt the TPM and PCR logs to acquire false attestations, effectively compromising the Device Health Attestation validation process.
