A Move to Secure Data by Scattering the Pieces

Posted by ryuzaki0 on from the can-you-find-me-now dept.

uler writes "The NY Times has an article about an interesting new open source storage project. Unlike data storage mechanisms today that work 'by making multiple copies of data,' the Cleversafe software takes an 'approach based on dispersing data in encrypted slices.' It's an elegant solution and one that's been a long time coming: the software uses algorithmic techniques known by mathematicians since the 70's. Adi Shamir (of RSA) first wrote of information dispersal is his 1979 paper 'How to Share a Secret (pdf).'"

    Although the goal was different, this is in the spirit of the creation of the Internet. DARPAnet was designed to scatter information to maintain communications. to use a different example it reminds me of RAID.


    With all of this encryption technology, people still need to remember basic security tips. Use good passwords ("password" could be cracked very quickly even with 128 bit AES), maintain physical security (hardware keyloggers can find out about the manifesto you're writing before you even save the file) and use common sense.


    Before you all ask, yes it does run Linux. The company was actually at Linuxworld.

      Cite? From what I've read about the original Arpanet, it was designed to allow the sharing of computer resources and data among DoD researchers. It wasn't designed to be a failure-tolerant network, although DARPA funded quite a bit of research in that area.

  3. Like mnet? by haeger · · Score: 4, Insightful
    If I'm not mistaken, this was one of the goals with the (now dead?) mnet project.
    From what I remember they split up data into multiple pieces, encrypted it and distributed it over a number of nodes, with some redundancy in it. If you know python and are intrested in p2p I'm sure there's a lot to be learned from that project.
