Abstract
Several methods and a system of multilayer encryption of a transport stream data and modification of a transport header are disclosed. An exemplary embodiment provides a method of a multilayer encryption. The method includes further encrypting an initially encrypted transport stream data to generate a multilayer encrypted data using a processor and a memory. The method also includes determining a further encryption flag data. The encryption method modifies a transport header of the multilayer encrypted data. In addition, the encryption method includes the further encryption flag data in an adapted component of a modified transport header.
