Normative References [FIPS197] National Institute of Standards. "FIPS Pub 197: Advanced Encryption Standard (AES)", 26 November 2001. [LUHN] Luhn, H., "Luhn algorithm", US Patent 2950048, August 1960, http://patft.uspto.gov/netacgi/nph- Parser?patentnumber=2950048. I cannot find a patent disclosure about this on file with the IETF: https://datatracker.ietf.org/ipr/search/?option=document_search&document_search=draft-ietf-keyprov-symmetrickeyformat I believe the authors should file a patent disclosure about this in order to comply with the spirit of RFC 3979 section 6.1.3. Was the patent concern discussed by the WG before the last call? I don't recall any discussion about this, but I may have missed it. What is the licensing for this patent? Use of the LUHN algorithm does not appear essential for this document, thus I would prefer that some other non patent encumbered algorithm were used. /Simon _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
