1. An electronic gaming system for providing authentication of a data set associated with a casino type game, said system comprising:
- (a) a first storage means for storing a game data set and a game signature comprising an encrypted version of a unique primary abbreviated game bit string computed from said game data set;
(b) a second storage means for storing, an anchor application including a first authentication program capable of determining the validity of said game data set by, computing a complementary abbreviated game bit string from said game data set, decrypting said game signature set to recover said primary abbreviated game bit string, comparing said complementary abbreviated game bit string with said primary abbreviated game bit string to determine whether a match is present, and an anchor signature including an encrypted version of a unique primary abbreviated anchor bit string computed from said anchor application;
(c) a third storage means for storing a second authentication program capable of determining the validity of said anchor application by, computing a complementary abbreviated anchor bit string from said anchor application, decrypting said anchor signature to recover said primary abbreviated anchor bit string, and comparing said complementary abbreviated anchor bit string with said primary abbreviated anchor bit string to determine whether a match is present; and
(d) processing means for enabling said first authentication program to determine the validity of said game data set and for enabling said second authentication program to determine the validity of said anchor application.

Abstract
The electronic casino gaming system consists of several system components, including a microprocessor (12), a main memory unit (13) that is typically a random access memory, and a system boot ROM (14). Also included in the electronic casino gaming system are a non-volatile RAM (17), a mass storage unit (18), a disk subsystem (19), and a PCI bus (20). The disk subsystem (19) preferably supports SCSI-2 with options of fast and wide. A video subsystem (22) is also included in the electronic casino gaming system and is coupled to the PCI bus (20) to provide full color still images and MPEG movies.

16. A casino gaming apparatus, comprising:
-
a casino game console;
a video display unit;
a main memory providing an executable space for a processor, said main memory being disposed in said casino game console;
a disk memory having gaming data relating to a casino game stored therein;
a nonvolatile memory operable to store gaming data at least related to the play of the casino game; and
a memory storing an operating system, said memory being disposed in said casino game console, wherein the operating system is enabled to control the disk memory and wherein the operating system is authenticated prior to the gaming data relating to the casino game;
the processor disposed in said casino game console and being operatively coupled to said video display unit, said main memory, said nonvolatile memory, said memory and said disk memory, said processor operable to cause said gaming data stored in said disk memory to be transferred to said main memory, said processor operable to cause said gaming data that was transferred from said disk memory to said main memory to be authenticated based on comparison of a message digest generated by performing a one-way hash function on said gaming data being authenticated with a message digest previously generated by performing a one-way hash function on known gaming data, each of said one-way hash functions producing a fixed-size string of bits, and said processor causing a remedial action to be taken if said gaming data transferred from said disk memory to said main memory is not authentic as determined by said processor. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
