Under http://www.ipjur.com/pki.pdf I have posted a document "Trilateral Technical Standard for the On-line Exchange of IP Documents in a PKI Environment" dated November 05, 1999. It conveys a commpon position of the European Patent Office, the US Patent Office, and the Japanese Patent Office on a crypto standard for electronic filing of patent applications and the like. In general it seems to be not so bad (relying on well-known standards) but there are somewhat unclear text portions on key recovery. Axel H Horns
