Abstract
Systems and methods described herein include wagering game systems that communicate with servers or other entities in a wagering game network using multicast groups. Data transmitted over the network for the multicast group is encrypted. Keys for the encryption and decryption of the data are generated based on a current key index for the multicast group, and a global passphrase. The global passphrase is not transmitted over the network.
