Methods and apparatus for distribution of global encryption key in a wireless transport network

摘要

A method of providing encryption service in a wireless transport network comprises the step of designating a first wireless device as a global encryption key server to create and maintain the global encryption key for a wireless transport network encryption. Nest step is to distribute the global encryption key from the first wireless device to a second wireless device in the wireless transport network. The existing global encryption key in the second wireless device is replaced by the global encryption key. Further step is to transit an expiring global encryption key to a new global encryption key in the wireless transport network without traffic loss and security.
