Digital signature issues on the table

[MURATA Makoto]

Folks,

JNSA and the Japanese mirror plan to provide a detailed proposal for
the intrudction of XAdES into OPC.  While preparing for this proposal,
we are also reconsidering OPC digital signatures in general.

Here is a list of issues on our table now.  My two cents are
parenthesized.

1) DSig version: 1.1? (1.1 only)

2) Canonicalization algorithms?  (1.0, 1.1, and ExcC14N)

3) XAdES Version: EN or TS? (EN only)

4) Which spec from ETSI?  (Part 1 of XAdES as well as AdES)

5) New relationship type for XAdES EN digital signatures part? (Yes)

6) SignatureTime of OPC?  (Disallowed in XAdES EN digital signatures)

Regards,

Makoto
