May 2026: Are hybrid or post-quantum cryptographic key-transport mechanisms permitted for HSMs? A) Yes. Hybrid and pure post-quantum cryptographic (PQC) key-transport mechanisms are permitted, provided that:

• Each individual cryptographic component (whether classical or PQC-based) independently meets or exceeds the minimum cryptographic strength as enumerated in the table below.

• Mutual authentication must be enforced.

• All key transport follows basic key management principles, including cryptographic binding of key usage attributes to the transported key (i.e., use of a compliant Key Block as defined in the applicable key block requirements, such as those based on ANSI X9.143, ISO 20038, or ASC X9 TR-34 principles).

• The key block must include, at minimum:

• Attributes defining the permitted operations for the key.

• Attributes defining the cryptographic algorithm and mode of use.

• Attributes defining exportability of the key.

• Use of key-length obfuscation padding for symmetric keys to the maximum length for the algorithm, 192 bits for TDEA …

May 2011: If a device complies with B15, does this mean I need to re-submit the device for lab evaluation every time I change the prompts? A If there are suitable wildcards in the firmware version listing to accommodate new prompt versions that have been previously reviewed and confirmed as appropriate by a PCI laboratory, the review of each change by a PCI laboratory is not necessary.
