Abstract

A system for distributing content in a network comprises memory that stores content. A provider network device communicates with the memory and wirelessly communicates with a requester network device that requests a copy of the content. The provider network device determines a local/remote status of the requester network device, transmits a key request to the requester network device when the requester network device has a local status, receives a key from the requester network device, encrypts the content with the key and transmits the encrypted content to the requester network device.
