System and method for downloading electronic information to a video lottery
First Claim
1. A gaming terminal comprising:
- a memory configured to store an encrypted master reset component;
a receiving component configured to receive a non-resident security key;
a decrypting component is configured to decrypt the encrypted master reset component into a decrypted master reset component; and
a processor configured to reset the gaming terminal to an initial state by executing the decrypted master reset component and effecting a master reset of the gaming terminal.

Abstract
This invention relates to reprogramming of in-circuit programmable chips installed in video lottery terminals (VLTs) by downloading electronic information (software) to such chips. Encrypted electronic information is downloaded from a host device to a gaming terminal through a communications link. The terminal comprises a decryption component configured for decrypting the encrypted electronic information using at least two security keys, at least one said key being resident in the terminal and at least another said key being delivered to the terminal at the time of the downloading (the downloading facilitating a replacement of existing software in terminal with corresponding decrypted software obtained from decrypting the encrypted information). The encrypted information transmitted to the terminal comprises at least one next version key for later use by the decryption component in decrypting a next version of encrypted electronic information. The non-resident key may be provided to the terminal by means of an electronic plug-in security key or provided through a secure network.
