Apparatus and method for communication security in a nationwide wireless network using wireless routers

摘要

Systems and methods for security in a nationwide wireless network with geographically dispersed wireless routers are described. The wireless routers have an interface function with an ability to receive telephone calls from an authorized caller. The router, in response to a received call from the authorized caller, generates a set of bounded random numbers (BRNs) as a random seed for use in generation of encryption keys for communication security between the router and a portable wireless device of the caller.
