US 2010/0304807 A1 · HASH FUNCTION USING A CUE SPORTS GAME PROCESS

Abstract

In the computer data security field, cryptographic hash function processes embodied in a computer system and which are typically keyless, but are highly secure. The processes are based on the type of randomness exhibited by well known table “cue sports” games such as billiards, snooker, and pool played on a billiards table involving the players striking one of a plurality of balls with a cue, the struck ball then hitting other balls, the raised sides of the table, and in some cases one or more balls going into pockets in the corners and/or sides of the table. Computation of the hash value (digest) is the result of providing a model (such as expressed in computer code) of such a game algorithm and using the message as an input to the game algorithm, then executing the game algorithm. A state of the game after one or several “shots” gives the hash digest value of the message.

Dependent claims

A hashing method performed by a computing apparatus and comprising the acts of:

(a) receiving a message at an input port;
(b) storing the received message as a table having a plurality of entries in a first computer readable storage medium coupled to the input port;
(c) a processor coupled to the first storage medium selecting a first of the entries of the stored message as a current position;
(d) the processor selecting a second of the entries as a target;
(e) the processor determining and storing an energy value in a second computer readable storage medium coupled to the processor;
(f) the processor computing, according to a cue sports algorithm, entries for the table as a function of the first and second entries and the energy value;
(g) updating the table according to act (f);
(h) using the updated table resulting from act (g) to provide a hash value of the message;
and
(i) the processor storing the hash value in a third computer readable storage medium.
