Title: Secure multicast content delivery

Abstract: In one embodiment, a method for establishing a secure multicast channel between a service provider and a terminal is provided. A request is received from the service provider for a configuration of the terminal. A configuration of the terminal at a first time is sent to the service provider. A security key is obtained, wherein the security is bound to the configuration of the terminal at the first time. Then the security key is decrypted using a configuration of the terminal at a second time, wherein the decryption fails if the configuration of the terminal at the second time is not identical to the configuration of the terminal at the first time. A secure multicast channel is then established with the service provider using the security key.
