Patent ID: 8654976

Claim:
A system of communication security in a mobile wireless communication device, comprising: a. the system has executable instructions that are stored in a memory of the communication device and operative there from in a CPU of the communication device for a function that maintains a table in a memory of a caller communication device that maps a list of caller ids of mobile devices to a list of set of bounded random numbers, where the set of bounded random numbers correspond to at least the cycle times and amplitudes of at least three different wave types that include a triangle, a square, or a sine wave; b. a function, that at a time of an outgoing communication from the caller communication device, retrieves from the table, a set of bounded random numbers corresponding to a caller id of a called device and uses that set to derive a sequence of encryption keys; and c. a function that encrypts a sequence of communication packets outgoing from the device to the called device with the corresponding sequence of encryption keys for a secure outgoing communication.
