A method is implemented by a network device operating as a content node for securely distributing a content object over an information centric networking (ICN) network. The method implements a unique obscured retrieval sequence. The method includes receiving an interest for a chunk of the content object from a client device, where the chunk is identified with an obscured chunk identifier, translating the obscured chunk identifier into a general chunk identifier for the content object, and sending the chunk of the content object to the client device.
