Subject: RE: [pkcs11] Groups - EdDSA Using Additional Key Types uploaded
Hi Darren, Thank you for submitting the 3 draft proposals for support of Edwards curves. Our position is the following: ·
Proposal 1) : re-using existing key types seems difficult, and doesn’t
really make sense (except when using the Weierstrass form, which technically works (we implemented it, and it works fine) but is not intuitive for users/application developers). ·
Proposal 2) : is ok, but introduces a completely new scheme, algorithm and key type ·
Proposal 3) : this is our preferred proposal: on the one side, users/application developers will easily get familiar with it as uses the same approach they know from
ECDSA/ECDH implementations; on the other side, the new key types allow for Edwards-/Montgomery-specific representation and handling at low-level, and thus avoid squeezing these curves into a corset as proposal 1) would do I’ll be happy to hear/read other people’s
opinion as well. Thanks, Dieter From: pkcs11@lists.oasis-open.org [mailto:pkcs11@lists.oasis-open.org]
