Abstract: A content processing integrated circuit includes a system-on-a-chip (SoC) that further includes a processor to receive an authentication request from an external device for authenticating if the SoC is permitted to receive encrypted content from the external device, and to receive the encrypted content once the SoC is authenticated. An authentication processor is provided and coupled to the processor to authenticate the SoC to the external device when the processor receives the authentication request, and to generate a decryption key for decrypting the encrypted content. A decryption processor is provided and coupled to the processor and the authentication processor to receive the decryption key from the authentication processor and to decrypt the encrypted content with the decryption key. A wireless display system with such SoC is also described. A method of implementing a secure and robust content protection in a SoC is also described.
