A casino game is implemented on the basis of a wireless mobile player unit adapted to play poker, slots, bingo and other casino games. The unit obtains random game outcomes from a central computer over a radio channel utilizing a data authentication and/or encryption technique relying on a database of authentication keys. The authentication key database and, optionally, key selection criteria are downloaded into the unit from the central computer via a secure communication channel. The data authentication key database is preferably used only once, and is replaced with a new database for each session. Alternatively, a database of keys may be resident on the player unit and an encryption selection sequence or algorithm is securely downloaded before the start of a gaming session, which is then used to choose a different authentication key for each transaction occurring during the session. Authentication keys may also be used as encryption keys to further protect the data. An encryption key database and/or selection criteria may be generated by either the central computer, the player unit or a combination of both.
