Claim 1:
2. The method of claim 1, further comprising:
a surface bin, b, for which at least one certain edge does not point to any neighboring bin, another bin of the key is regarded as the pointed-to neighboring bin, b*, instead of the missing neighbor; the pointed-to “virtual neighbor” bin, b* is being determined by identifying the bin most distant from b, when measured in the direction opposite to the direction of the edge that pointed to no neighboring edge, thereby for every bin in the key there are e edges pointing to e neighboring bins,
and further utilizing Walk encryption, the move from b to b* is regarded as a step in the travel path, with that step marked with the ciphertext letter of the edge pointing to a missing bin.
