Abstract

Techniques are disclosed for secure playback of protected multimedia content on a game console using a secret-less application. An SSO model can be used for client authentication at a key server, which eliminates the need of storing or using any secret information in the client application. Further, an encrypted content key generated by a content packager using a public key can be deployed in the key URI of a playlist file, which is sent to the key server. The key server can be configured to decrypt the content key using a corresponding private key. Further, the content key and unencrypted samples are protected in the game console client application from debugging and replay attacks by using additional security checks at both the client and key server. By storing secret information remotely from the game console and using the SSO model, DRM policies can be enforced on an untrusted client application.
