After a conversation with Shalom, Tom Fitzpatrick, and Neil Korpusik,
we identified a set of clarifications that are intended to bettter
reflect the intent of the Encryption Committee. Shalom needs these
changes by the end of today in order to reflect them into the final
draft for ballot circulation. Further issues and changes will need
to be applied following ballot resolution, for the recirculation.
With the consent of the committee (please object to any portion you
wish to discuss in committee before incorporation into the draft),
Shalom will update the final ballot draft with the attached changes.
Any items that for which an objection is expressed should not be
applied to the draft, and we will consider that issue for the
I appreciate the committee's review on such short notice, and will
understand if anyone feels that action should be deferred until
the recirculation. However if there is consensus that these
changes are non-controversial, the ballot review should go much
To address the questions raised in I015, add the following text at the end of the 3rd paragraph of 28.2.1 "Encryption":
In Table 28-1 (for data_decrypt_key and digest_decrypt_key), replace:
encryption session key
encryption session key
To clarify the conformance expectations (see I006), add the following paragraph immediately befor 28.2.1 "Encryption":
Tools that process the Verilog HDL shall perform envelope decryption for all decryption envelopes contained in the source text, where the proper key is supplied by the user. Tools that perform envelope encryption shall only be required to process the protect pragma directives, and shall apply no other interpretation to text which is not part of a protect pragma directive.
28.3 Envelope Directives
and replace sub-clause title:
28.3.1 Envelope encoding keywords
28.3.1 Envelope encoding keywords protect Pragma Keywords
Verilog tools that support decrypting compilation shall transform source text containing decryption envelopes by replacing each decryption envelope with the decrypted source text according to the specified pragma expressions. This substitution shall occur in a manner similar to and at a translation phase consistent with that of macro substitution. Unless otherwise specified, occurrences of the protect pragma directive shall not be included in the decrypted source text which replaces the decryption envelope.
Verilog tools that support decrypting compilation shall transform source text containing decryption envelopes by replacing each decryption envelope with the decrypted source text from the data_block, according to the specified pragma expressions. The substituted text may contain usages of text macros, which shall be substituted after replacement of the decryption envelope. The substituted text may also contain decryption envelopes which shall be decrypted and substituted after replacement of their enclosing decryption envelope.
