When using Amazon GameOn, you will notice that there is a requirement for creating public / private key pairs and encrypting payloads (e.g. using RSA Encryption around Auth and Prize Tokens).
It might seem that implementing the encryption is burdensome, however many game developers employ game servers to send game traffic between Amazon and their player.
By using End-to-End Encryption, it allows GameOn to send secured messages over those intermediate game servers while ensuring integrity of the Prize.
Therefore, this extra TLS Crypto steps allow for Auth and Prize Tokens to be sent over open game networks, and prevent attacks, such as Man in the Middle attacks. To help our developers get started faster, we currently provide a Unity / C# reference implementation, and we hope to have reference implementation for more platforms in the future.
