  A scheme is presented based on numbers that represent a manifold in $d$
dimensions for generalizations of textbook cryptosystems. The interlocking or
intersection of geometries, requiring the addition of a series of integers
$q_j$, can be used to enhance a cryptosystem via algorithms based on the form
of the geometry. Further operations besides addition of these numbers, e.g.
sewing of the geometries, can be given such as rotations or contractions.
