Notes

• Discussed open PRs and Issues.
• Discussed the suitability of hash-to-scalar as an alternative of the HKDF based KeyGen operation. It was agreed that hash-to-scalar is most likely a good replacement for HKDF KeyGen.
• Discussed alternative to hash-to-scalar that does not depend to exapnd_message from the hash to curve spec, and more specifically the approach from section 5 of [CDMP07].
• Similarly, discussed alternative to hash-to-curve for creating generators and more specifically the approach from section 3.3 of [BLS01].
