  • Patent number: 8107622
    Abstract: A data hashing system operative to hash an incoming string of message words is an object of the present invention. The system generates a hash value tag comprising a deterministic random number string which uniquely identifies the incoming string. The system comprises at least first and second register arrays, at least one 1-way functionality in at least pseudo-randomizing function; and a set of at least first and second orthogonal feedback word stream generators operative to generate a set of at least first and second orthogonal feedback streams of message words respectively, including applying respective permutations to the incoming string.

    Abstract: A data hashing system operative to hash an incoming string of message words, thereby to generate a hash value tag comprising a deterministic random number string which uniquely identifies the incoming string, the system comprising at least first and second register arrays, at least one 1-way at least pseudo-randomizing functionality; and a set of at least first and second orthogonal feedback word stream generators operative to generate a set of at least first and second orthogonal feedback streams of message words respectively, including applying respective permutations to the incoming string, wherein the first and second feedback streams are combined into the first and second register arrays respectively, the at least pseudo-randomizing functionality accepts input from the register arrays and generates at least pseudo-random output which, in combination with a present word in the incoming string, is provided to the stream generators, and the first feedback stream is a first function of a present word in the
