Currently, the opennet proposal includes an announcement mechanism where the node to be announced chooses its location, sends off an announcement request, and is provided with a bunch of connections near that location (and leading up to it).
This is arguably insecure; freenet 0.5 had an announcement mechanism where the network would choose a random location for the node, and give it some keys and some connections somewhere near it. However, it should be possible to target a specific location simply by (inserting and) requesting lots of keys near to it... With a large network this gets expensive as you have to either know lots of keys, or create keys which are close to the target. Are routed announcements a problem? It is not possible to generate a location randomly then route to it, because an attacker would just use the latter stage. Routed announcements do have the advantage of getting the right connections right at the beginning; nodes can start opennet very quickly. -------------- next part -------------- A non-text attachment was scrubbed...
