Abstract

A method for accessing content stored on a memory device is provided. In this method, a request to access the content is transmitted and a session ticket is received. The session ticket includes a parameter used to decrypt the content and the session ticket is generated based on a variable that is configured to change at a session. The content may be accessed based on the session ticket. An apparatus is also provided comprising a memory and a processor in communication with the memory. The processor is configured to: transmit a request to a memory device to access content stored in the memory device; receive a session ticket; and access the content based on the session ticket. The session ticket includes a parameter used to decrypt the content and the session ticket is generated based on a number that is configured to change at a session.
