ABSTRACT:
An authentication system is disclosed. The authentication system includes a content provider configured to distribute encrypted content, wherein the encrypted content is generated using a content key, and a client having a symmetric key and configured to store the encrypted content received from the content provider and issue a request to the content provider, wherein the request includes a cryptographic function configured to have the symmetric key and the encrypted content as input, wherein the content provider is further configured to verify the client via the request to ensure that the client has received the encrypted content.
