Title:
Polar Lattice Cryptography
Authors: Gideon Samid
Abstract:Presenting a protocol that builds a cryptographic solution which shifts security responsibility from the cipher designer to the cipher user. The Polar Lattice is a pattern-devoid cryptographic cipher. It is based on a geometric construct – a polar lattice, on which the letters of a plaintext alphabet A, are presented as two points each letter, so that to transmit a letter the transmitter transmits a randomized pathway, a trail, (ciphertext) that begins at the first point of the transmitted letter and ends at the second point of the transmitted letter; the transmitted pathway is a set of steps on the lattice. Once a letter is transmitted the next bits on the ciphertext mark the beginning of the pathway that points to the next letter. The size and the geometric construction of the polar lattice are randomized and kept secret. The randomized pathways may be long or short, the attacker does not know how to parcel the ciphertext to individual trails pointing to distinct letters in the plaintext alphabet A. The polar lattice may be implemented algebraically, or geometrically; the lattice may be a physical nano-construct. The polar lattice is very power efficient, very fast. It claims all the attributes associated with pattern devoid cryptography: it allows for only brute force cryptanalysis, which in turn can be defeated through increased ciphertext size, unlimited key size and structure complexity.
