[Gzz] 12th (Benja)

[Benja Fallenstein]

Trying to get back to writing daily reports. I'm not very good at 
keeping up the discipline. :-(  (I wouldn't mind if somebody would pm me 
with a short note when I'm obviously starting to forget it again...)

- Processing [dtnrg-interest] mail (DTN is for delay-tolerant network, 
the generalization of interplanetary internetworking that may be useful 
for Tuomas' ideas about scheduling tasks while offline).
- Learning about IBP (Internet Backplane, a system for sharing storage 
and keeping storage along network routes-- for example to cache data-- 
that is currently in use with 5TB of storage distributed over the US, 
Europe and Asia; there's a proposal to use IBP as a storage layer for DTN).
- Thinking about DTN/p2p network bridging. (We want to be able to queue 
a request to a DHT.)
- A bit of thinking about security issues with the Storm extension 
proposal Tuomas and I discussed on the list: So far, we were planning to 
store 20 random bytes in the *header*; with the proposal, that would 
lead to the counter-intuitive situation that distributing the header may 
give away parts of the body: if 90% of the body are already known, with 
them and the header the rest may be reconstructible by brute force. This 
is counter-intuitive because the header refers to the body only through 
cryptographic hashes; programmers might assume that giving the header by 
itself away cannot do harm, which is wrong.
