One important feature of the SERVANT network is that it provides anonymity. It's not just about you cannot know who initiate a STORE or who initiated a GET. You have anonymity for all messages (except the ones that where put in to allow grading). All messages are either flooded or forwarded. So, a node can deny that it's the recipient of a message and claim that it's only forwarding a message. Similarly, a node can deny that it's the origin of a message and claim that it's only forwarding a message. This way, unless the authority can record most of the traffic in the SERVANT network, it would be difficult for the authority to figure out exactly who initiated a message and who was the intended recipient of the message. -- Bill Cheng // bill.cheng@usc.edu On Sat, Nov 22, 2008 at 8:27 AM, Bill Cheng wrote: > Someone wrote: > > > When get message is flooded, suppose a node gets the message and > > identifies the fileid and sha1 as being the ones that belong to a file > > it has, then should it send the get response and not flood the request > > or should it still flood the request message. > > It should continue to flood the GET request for the reason > of plausible deniability. > -- > Bill Cheng // bill.cheng@usc.edu
