  2. From the hash-based-passwords dept.? on Safari and Chrome: Tied For the Worst Password Manager · · Score: 1

    I think the "real" solution, if you want good password security, is to use the following scheme:

    pwd = hash(master_secret || site_id || site_counter).

    That is, use as a password the hash value of your master password, something that identifies the site you're logging in at (say, "slashdot" for everything at slashdot.org), and a generation counter such that if your slashdot password gets stolen you can make a new one without changing your master password (and without changing password on your ~gazillion accounts).

    There's a firefox plugin which does something like this, at http://crypto.stanford.edu/PwdHash/. It has the advantage that it doesn't require you to store any information [except your master password in your brain], and so you can compute your password on a friend's computer by visiting their webpage.

    I think a solution based on this idea provides the best combination of usability and security. Note that you can of course still use different master passwords for different sites if you want.

  7. Re:Captain disillusion on BitTorrent For Enterprise File Distribution? · · Score: 1

    Yes the ISP's routers could get compromised, but that's the whole point of IPsec - so that someone in the middle can't read your traffic.

    They can do traffic analysis to see which protocol(s) you're using. They can launch attacks against your boxes. They can start messing with BGP.

    If someone wants to be evil towards you, having them break into your ISP routers is bad. Without encryption it's worse, but with encryption it's still bad.

    What I found is that a machine that costs 10 megadollars can break 1024bit RSA in a year; I think it was key recovery, not just message recovery. Depending on who you think your adversary is, this might make you uneasy.

  8. Re:Captain disillusion on BitTorrent For Enterprise File Distribution? · · Score: 1

    You don't even have to calculate the difference between updates to push just the difference

    I think it'd help

    bittorrent automatically splits the files up into chunks which it calculates the md5 to.

    It uses sha1, not md5: http://en.wikipedia.org/wiki/BitTorrent_(protocol)

    If you set it up right bittorrent will calculate the [hash value]s of all the chunks of the previous update and update only the chunks with different [hash value]s

    So if you push_front a singe 0, every chunk will change (they all have the same size, which you can configure), so you have to download everything again.

    If you do compression with an infinite window, it's likely that a single small change in the source will change a lot in the compression.

    Computing the diff seems like it most reliably will limit your bandwidth usage.

    with IPsec over DSL, and no access to the public internet.

    Unless you have very long wires, some box is going to route them. Are those your own?

    Otherwise, your ISP's router, diligent in separating traffic though it may be, can get hacked.

    Why am I saying this? Not to make you don your tinfoil hat, certainly, but just to point out that if the scenario is as I describe, you're not 100% GUARANTEED to be invulnerable. Maybe a few tinfoil strips in your hair would look nice... ;)

    About the actual question: bit torrent would probably be fine, but if most of the data is unchanged between updates, you may want to compute the diff and then BT-share that. How do you store the data? If it's just a big tar(.gz|.bz2) archive, bsdiff might be your friend.

    If you push from a single seeder to many clients, maybe multicast would be a good solution. But that's in the early design phase I think, which is not what you need :)

    Best of luck!

    The in-game ads in Guitar Hero III were completely immersion-breaking for me. It's a small part of why I've stopped supporting that series.

    I've gold-starred all of easy, all of medium except [tier 8, Don't Hold back, FCPREMIX, TTFAF], five-starred tier 1-6 on hard and at least half the bonus tracks with ~15 gold stars, and I'm only Raining Blood and Battle With Lou short of completing expert.
