摘要:
A method for enabling an access device to securely access content from at least a content provider and prevent a cloned access device from accessing such content. During registration of the access device with the content provider, the access device requests from a designated certificate authority a certificate having a public key of the content provider therein. Upon authentication of the certificate, the access device generates a key and uses the public key to exchange the key with the content provider. The key is then used for subsequent secure communications between the access device and the content provider. In this manner, a cloned device does not have access to the key and is unable to download content from the content provider.
