1. A method for accessing content stored on a memory device, comprising:

  • generating a session ticket by encrypting a parameter associated with the cryptographic key with a variable that has a value associated with a session and that changes value at different sessions;

    providing the session ticket to a host computing device;

    receiving the session ticket and a request to access the content from the host computing device;

    attempting to extract the parameter associated with the cryptographic key from the session ticket by decrypting the session ticket with the variable, wherein if the session has not changed, the value of the variable has not changed, and the parameter associated with the cryptographic key is extracted from the session ticket; and

    if the parameter associated with the cryptographic key is extracted from the session ticket;

    obtaining the cryptographic key based on the parameter,decrypting the content using the cryptographic key, andsending the content to the host computing device.
