I wanted to raise an issue to the list that has resulted from adding the Additional ECC Algorithms into the KMIP 1.2 specification – see section 9.1.3.2.5. The ECC algorithms are specified in multiple source documents and in several instances the same algorithm is known by multiple names since it is defined in multiple sources. When the ECC algorithm proposal was prepared for KMIP 1.2 a separate enumeration was given to each ‘named’ algorithm. So this means we now have the same algorithm with multiple enumerations. These duplications are highlighted in the table below (which is presently in section 3.42 of the KMIP 1.2 Usage Guide).

I don’t believe it is good practice to represent the same algorithm with multiple enumerations and I believe we should edit the enumerations so each algorithm has only one enumeration. We can update the table in the UG to show the mapping of the enumeration to each of its names.

What do others in the TC think? Should we make this change to the Spec and UG or should we leave things as specified in the Additional ECC Algorithm proposal?
