Subject: Re: [pkcs11] Groups - pkcs11-cka_uuid-wrapWithUUID-cka-derive-template.docx uploaded


Michael,

I have a few questions:
1)
Has anyone question you or comment about this proposal ?

2)
For CKA_UUID, it means, universally unique ID, right ? If that's the case, what is scope of this uniqueness ? I mean, you cannot guarantee the uniqueness across the internet, but perhaps, within a scope.

3)
For CKA_UUID and CKA_WRAP_WITH_UUID, can the implementor choose not to implement this field ? Can it be of type CK_BYTE_PTR or something ? Or, when the whole thing is zero 0x00000000000....000, it means, not applicable ?


Thanks,
Oscar

This is the formal submission for CKA_UUID and CKA_WRAP_WITH_UUID. It is also the formal submission for CKA_DERIVE_TEMPLATE (not previously described) and a slight update in the wording for CKA_UNWRAP_TEMPLATE with respect to how that template can be changed.

Document Name: pkcs11-cka_uuid-wrapWithUUID-cka-derive-template.docx

Description
Three items here, but did this as a single document since the edits were
all in this section:

1) Fixing the text on CKA_UNWRAP_TEMPLATE to indicate it can be set once
and then is read-only.

2) Adding CKA_UUID and CKA_WRAP_WITH_UUID. The first attribute marks each
key with a pseudo-random UUID that changes anytime the key changes. The
second points to the first for the purpose of uniquely identifying a key
that can be used to wrap this key.

3) Added CKA_DERIVE_TEMPLATE. This exactly mirrors CKA_UNWRAP_TEMPLATE in
that it is applied to a key derived from the key this attribute is on.
This is necessary to set things like the sensitivity or extractability of
derived keys.
