Ciphers as One-Way Function Synthesising
Writing a difficult cipher that is highly prone to attention from cryptanalysts is a poor second prize to using a definitive one-way function if it exists in the data-type being used, by the cryptographer. Such a cipher can never be accorded theoretically secure standard by the authorities and instead may be given only practically secure designation according to the amount of intractability that can be demonstrated for it.
A one-way function may be selectively moderated to a one-way trapdoor function that enables Alice and Bob sole control of the only inverse process (the trapdoor) by which they may then control its use for secure communications between them.
Vector based cryptography can be demonstrated as possessing such a one-way function by means of the change-of-origin ploy to the frame of reference in which the vectors are defined, thus leading to the one-way trapdoor function described.
