Issue Description

Version 1.2 of the Errata and Interpretation for CC:2022 (Release 1) and CEM:2022 (Release 1) updated the wording of several SFRs included in the protection profile.

Resolution

FCS_RBG.1, FCS_RBG.2, FCS_RBG.5 are updated to match the wording in the Errata v1.2. Other Errata v1.2 changes were already incorporated in cPP_DSC_V2.1 as refinements; they are not included in this TD. The references are updated to refer to the latest version of the Errata.

cPP_DSC_V2.1

The cPP is updated as follows (yellow highlights for additions, strikethrough for deletions) per section that is being updated:

FCS_RBG.1

FCS_RBG.1.1 is updated as follows:

FCS_RBG.1.1

The TSF shall perform deterministic random bit generation services using [selection: DRBG algorithm] in accordance with [selection: list of standards] after initialization with a seed.

FCS_RBG.2

FCS_RBG.2.1 is updated as follows:

FCS_RBG.2.1

The TSF shall be able to accept a minimum input of [assignment: minimum input length greater than zero] from a TSF interface for the purpose of obtaining entropy.

FCS_RBG.5

FCS_RBG.5.1 is updated as follows:

FCS_RBG.5.1

The TSF shall [selection: hash, concatenate and hash, xor, input into a linear feedback shift register, [assignment: combining operation]] [selection: output from TSF entropy source(s), input from TSF interface(s) for obtaining entropy] resulting in a minimum of [assignment: number of bits] bits of min-entropy to create the entropy input into the derivation function as defined in [selection: ISO/IEC 18031: 2011, NIST SP 800-90A Revision 1] resulting in a minimum of [assignment: number of bits] bits of min-entropy.
