><br>> <br>><br>> The only requirement for a swiss number is that it be unguessable. Cryptography is one way to generate such numbers, but there are others. For example, there's a guy at PARC who uses a Lava lamp. The numbers he generates are unguessable, but there's no cryptography involved. I think the name should reflect some essential property, not the means of obtaining that property.<br>
<br>IIRC, there is crypto involved: the image of the lava lamp is cryptographically hashed.<br><br>><br>> <br>><br>> ________________________<br>><br>> Alan Karp<br>><br>> Principal Scientist<br>><br>
