A secure first memory contains a boot program and a decryption key. When the gaming device, such as a stand-alone slot machine, is switched on, the boot program is used to download a start program from an external memory into a main memory. The start program contains a decryption algorithm. The start program is then used to download an encrypted gaming program from the external memory. The start program decrypts the gaming program using the code key from the first memory and stores the decrypted gaming program in the main memory. A main processor then carries out the gaming program when a player initiates play of the gaming device. Because of the special sequence of all steps to load the data, an unauthorized person cannot load different or changed programs to any of the memories. |
