    Actually the most important bit of information is the fact, that the card was cracked.

    I collect job adverts from newspapers. I know this sounds dumb, who uses newspaper adverts to find personnel these days?

    You don't really need it for logfiles - sequential writing is fast enough on non-SSD drives.

  4. Re:Moderated Torrent site on P2P BitTorrent Tool Could Replace Pirate Bay · · Score: 1

    Actually not that hard.

    I think Carnegie-Mellon people come up with a solution: instead of global "reputation" score use personal (local) one.

    Basically when you download stuff from people you mark them good or bad, then "the system" will cluster your opinions with others and provide you with scores to sources you don't know based on what people like you had to say about them.

    So you see - if for example Mediadefender starts to pull that trick with many fake users then they will be clustered together and won't have any impact on, well, "honest" downloaders.
    They can still build a reputation but it will go down the drain real fast as soon as they start to "use it".

  6. Re:Is this really necessary? on Fujitsu HDD with AES 256-bit Encryption · · Score: 1

    That's not really true in this case. If the drive allows access to the raw encrypted data and the key is known it is simple to audit the encryption hardware.

    That's very naive, to say the least.

    First of all, nobody gives access to actual platter information - what they write there can only be recovered in a lab. So in worst case scenario an audit like you described can be fooled by on-the-fly encryption of written data.

    But even if they correctly encrypt your data you don't know what else got written to the disk - i.e. the side channel information.

    And just from the top of my head (simply to further disprove your point about effectiveness of such an audit)look here: http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html (p. 7)

    So basically there are so many "holes" known and unknown, that without full disclosure of how they (Fujitsu) do that thing (including photolithography slides) such hardware encryption is unsuitable for "high stakes" situations.

  7. Re:Is this really necessary? on Fujitsu HDD with AES 256-bit Encryption · · Score: 2, Insightful

    What does that get you? Good device-level encryption already has the performance level of an unencrypted drive. The main thing - security. Software is open to everybody for extensive audit. Hardware on another hand, while potentially faster, not easily accessible and as such presumed insecure by default (one of the axioms of cryptography).

    So if you need real security - you do in-software full disk encryption, if you need performance and deniability - go hardware.
  8. Re:Is this really necessary? on Fujitsu HDD with AES 256-bit Encryption · · Score: 1

    Having a laptop stolen is a huge concern today. This will help ease that concern.

    That's the thing - stolen laptop is a liability. In many cases corporations don't really care if the data (with private information like soc security numbers) got stolen - they don't want public embarrassment and legal consequences. So for them - these hardware things are of great interest (as a form of due diligence defense).

    For real security - only open (audited) hardware/software solutions are acceptable.

    Any evidence of either of these assertions? *That* would be informative.

    The bottom line: if you really need cryptographic security - never trust solutions which are not subject to audit (i.e. not open source software/hardware)

    And the problem with most of what you said - it's illegal.
    What GP specifically mentioned is that the system (with secret data) was on when the warrant was issued/received (systems with unmounted encrypted volumes not discussed here - so no point mentioning that).
    Doing "stuff" with your computer after the warrant was received is "tampering".

    Not true.

    I personally never driven a car for more than 500 miles in one day.
    And I can count on my fingers how many times I drove for more than 300.
    And it's the same for most of the people.

    So, if I can recharge my car overnight - there is no problem with long charging times.

    It only takes a power plug at the parking space - it is trivial.

    For those few who really need to drive more than 500 miles a day (trucks) - gas is the answer (for quite some time in the future).

    The battery. It has only so much cycles in it. Basically, more you use it - faster it degrades. Read Tesla's blogs - if you add a plug to regular Prius and use it all the time your battery will be dead in 15 - 20k miles.
