Another is that the setup requires cooperation between Alice, Bob, and the proxy during key generation, so that (depending on what out-of-band semantics is imputed to the signature) one can impute some kind of authorization or consent by the parties to the re-signing.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-17908317.post-20144375172485442002007-09-04T15:44:00.000-07:002007-09-04T15:44:00.000-07:00See my paper, Elemental Subject Matter for how sof...See my paper, <A HREF="http://papers.ssrn.com/sol3/papers.cfm?abstract_id=936326" REL="nofollow">Elemental Subject Matter</A> for how software (including math) run on computers or stored in memory came to be patentable, even though algorithms and other math are not supposed to be patentable.
