re secret algorithm re clipper chip and crypto key escrow interestingly enough in designing the escrow we may want to use some rather unusual technology such as sealed boxes of paper or destructive read memory rather than typical computer databases which is fun for a database of hundreds of millions of keys the greatest danger of the escrow database if it were kept on disk would be the chance that a complete copy could somehow leak out you can design lots of protection but with enough corruption a complete copy is always possible storing it on paper or something very hard to copy at once may actually make sense or a medium that can t be copied for example something with very slow access times or which leaves a destructive trail if it is even read of course then it s hard to backup however i think the consequences of no backup the data is not there when a warrant comes are worse than the consequences of a secret backup an audit trail that reveals when data has been access that can t be erased by the humans involved is also necessary brad templeton clarinet communications corp sunnyvale ca
