A disclosed gaming machine may securely communicate with devices over a public network such as the Internet. The gaming machine utilizes a combination of symmetric and asymmetric encryption that allows a single gaming machine to securely communicate with a remote server using a public network. The secure communication methods may be used to transfer gaming software and gaming information between two gaming devices, such as between a game server and a gaming machine. For regulatory and tracking purposes, the transfer of gaming software between the two gaming devices may be authorized and monitored by a software authorization agent.
