Sep 6, 2007

Appl. No.:

11/896913

Inventors:

Frank John Kraszewski - Mundelein IL, US

Assignee:

PALTRONICS, INC. - Crystal Lake IL

International Classification:

H04L 9/00
H04K 1/00

US Classification:

380251, 380 44

Abstract:

The exemplary embodiments described herein relate to a light-weight encryption/decryption technique for peripherals (e.g., gaming machines, overhead displays, a jackpot controllers, etc.) attached to gaming networks. In certain exemplary embodiments, a peripheral device for use in a networked gaming environment is provided. A network interface is configured to send and receive at least one data stream, with each said data stream including at least a data block and a predetermined portion to be used in key generation. An encrypt table includes an index of random numbers in a predetermined range, with the encrypt table size and the range of the random numbers being set in dependence on the predetermined portion of the data stream. A decrypt table is provided, with the decrypt table being the inverse of the encrypt table. Key generating programmed logic circuitry is configured to generate a key in dependence on the predetermined portion of the data stream. Encrypting programmed logic circuitry is configured to generate an encrypted data stream by encrypting a data block of an unencrypted data stream for encrypted transmission via the network interface in dependence on the key and the encrypt table. Decrypting programmed logic circuitry is configured to generate a decrypted data stream by decrypting a data block of an encrypted data stream received by the network interface in dependence on the key and the decrypt table.

Abstract:

Systems and/or methods for displaying content on an LED display device comprising a plurality of LED modules are provided. A plurality of frames to be sequentially displayed on the LED display device across the plurality of LED modules may be defined based at least in part on the content to be displayed. A fieldcount corresponding to a number of scans appropriate for each said frame may be defined. For each said frame, the fieldcount for the frame may be initialized. The frame may be divided into a plurality of sequentially ordered rows and columns. For each said row, in sequence, a signal may be outputted to the LED display device in dependence on the frame, the fieldcount, the row, and the column. The fieldcount may be increased and the dividing step may be repeated until all scans of the frame have been completed. The content may be displayable substantially continuously and substantially free from flickers.
