Abstract
A method, computer system, and computer-readable medium with instructions to provide a client security management layer and a content player that ensure that the content is protected from malware on the receiving computer system. The client security management layer controls access to a protected portion of a memory of a computer system on behalf of a component, such as the content player, running on the processor of the computer system. The client security management layer receives an encrypted content key from the component, confirms the integrity of the component, decrypts the encrypted content key to provide a decrypted content key, and places the decrypted content key in the protected portion of the memory in response to confirming the integrity of the component. Other embodiments are described and claimed.
