1. A method for processing a data segment within a portion of a distributed storage network, the method comprising:

  • receiving a data segment;

    partitioning the data segment into a first portion and a second portion;

    determining a first hash value for the first portion;

    producing an encrypted second portion utilizing a first encryption key that is based at least in part on the first hash value;

    determining a second hash value of the encrypted second portion;

    producing an encrypted first portion utilizing a second encryption key that is based at least in part on the second hash value;

    combining the encrypted first portion and the encrypted second portion into an encrypted data segment; and

    outputting the encrypted data segment for further processing and storage in secure memory locations located across the distributed storage network.
