Abstract

A method for secure generation of a random number. An RNG sequence is generated using an RNG algorithm and an RNG seed. The current position within the RNG sequence is advanced every specified time interval. At intermittent intervals, the current position within the RNG sequence is advanced by a random amount.

Claims (11)

1 . A method for secure generation of a random number in a gaming system comprising:

generating an RNG sequence using an RNG algorithm and an RNG seed;

advancing the current position within the RNG sequence every specified time interval;

at intermittent intervals, advancing the current position with the RNG sequence by a random amount.

2 . A method as claimed in claim 1 , and further comprising:

upon action triggering the selection of a random number at the current position with the RNG sequence, generating a new RNG sequence using the RNG algorithm and a new RNG seed.

3 . A secure gaming system comprising:

a plurality of client monitors that display gaming activity and accept user input but do not contain any gaming intelligence or perform any gaming processing;

a game server coupled to the client monitors that receives the user input from the client monitors, processes the input according to a game selected by the user and a current output of an RNG, and returns a game outcome response to the client monitors, wherein

a plurality of separate RNGs corresponding to the plurality of client monitors are stored on the game server.

4 . A system as claimed in claim 3 , wherein the current output of the RNG is determined by constant advancement of the current position in an RNG sequence, and intermittent random advancements of the current position in the RNG sequence.
