50  - work towards making libvob and fenfire work on Kaffe  - work towards making libvob and fenfire work on Kaffe
51  - submit patches to Kaffe  - submit patches to Kaffe
52    - more thinking about vobs, trying to come up with
53      way to get started on structured graphics vobs
54    - learn about XML signature: can we come up with a way
55      to use one-time signatures with XML sig? (register
56      our own algorithm) -- actually doesn't require
57      registering: XML sig uses URIs! There are free
58      implementations of XML sig; however, we may consider
59      XML sig as too heavyweight (need to think).
60      We could also say: only RDF blocks are signed
61      (for RDF, meaning is more or less well-defined);
62      so the sig block simply gives the hash of the RDF block.
63      -- It's interesting that there is no standard
64      one-time signature algorithm-- I mean there are algorithms,
65      but abstract descriptions, not on the level that specifies
66      which exact bytes the output is for a given input.
67    - Think about timestamping; to provide non-repudability
68      (one can't say one signed a given block) one would need
69      to be able to prove that a block was signed before
70      the key was revoked? Otherwise to say you didn't sign
71      a given block, you'd just need to revoke the key that
72      signed it... and claim that the signature was created
73      after you've revoked the key. However, non-repudability
74      is not a central goal of Storm; it may be ok if it is
75      only archievable if a trusted third party timestamping
76      service is available.
77    - Figure out how at the expense of some more space & time,
78      one-time signatures can be made any-time; need to think
79      about whether that is useful... :-) [may not be new,
80      but if it is, may be publishable]
81    - Note that there are *many* introductions explaining that
82      one-time signatures can only be used one or a limited
83      number of times. Therefore, it seems this is new.
84    - Start writing this up. Notice that ACM CCS deadline
85      is tonight and make brave-hearted but folly-ish attempt
86      to write an article. ;-) Give up.
