and C) wherein said randomization procedure comprises the steps of: a) selecting a mathematical construct block in a logarithmic signature which consists of a plurality of mathematical construct blocks, said selected mathematical construct block consisting of at least two permutations of a sequential plurality of numbers, then selecting a permutation therein; then for said selected permutation selecting permutation(s), one each, from at least one alternative, other, mathematical construct block located below said selected mathematical construct block in said logarithmic signature; then multiplying said selected permutations in said selected mathematical construct block and in said alternative, other, mathematical construct blocks together and replacing said selected permutation in said selected mathematical construct block with the result of said multiplication, to form a replacement mathematical construct block for said selected mathematical construct block, and b) optionally repeating step a for other permutations in said selected mathematical construct block in said logarithmic signature; and then replacing said selected mathematical construct block in said logarithmic signature with said replacement mathematical construct block; and c. repeating step a but selecting an alternative, other, mathematical construct block in said logarithmic signature to be the selected mathematical construct block than was selected in the first application of step a; and then replacing said selected alternative, other, mathematical construct block in said logarithmic signature with said replacement mathematical construct block; and D) wherein said permutation shuffle comprises the step(s) of: a. identifying at least one pair of permutations in a selected mathematical construct block in a logarithmic signature, and optionally proceed to reverse the positions of said identified permutations in said mathematical construct block; and b) optionally repeating step a for other permutation pairs in said selected mathematical construct block in said logarithmic signature; and c) optionally repeating step a but modified by the selection of an alternative, other, mathematical construct block in said logarithmic signature; any of said: 1) commutation shuffle; 2) fusion procedure; 3) randomization procedure; and 4) permutation shuffle; being performed being performed only if, and only in a sequence, which provides that the property of logarithmic signatures requiring that logarithmic signatures be a collection of ordered mathematical construct blocks in which each input vector data key encrypted by utilization thereof can be uniquely represented as one, and only one composition of permutations which are present in said logarithmic signature, one such permutation being composed being selected from each of said logarithmic signature ordered mathematical construct blocks, is preserved.
