1. A method for independently generating one or more keys at two or more devices, the method comprising:
- transmitting a signal from the two or more devices;
receiving at each device a signal transmitted from the other one or more different devices;
processing the received signal at each device to obtain data based on movement of at least one of the devices with the respect to the other device;
and generating one or more keys based on the obtained data at each of the devices for use in securing communications between the devices, wherein the one or more keys at each of the devices is substantially the same.

Abstract
A method and system for generating one or more keys includes obtaining at two or more devices data based on movement of at least one of the devices with the respect to the other device. An RF signal sent from each of the one or more of the devices to the other devices is used to generate data that changes in accordance with the movement of the one or more devices. At least one key is generated based on the obtained data at each of the devices for use in securing communications between the devices. The key at each of the devices is substantially the same.

40. A system for independently generating one or more keys at two or more devices, the system comprises:
-
a transmitting for transmitting a signal from the two or more devices; a receiver at each device for receiving a signal transmitted from the other one or more different devices; a data acquisition system at each of two or more devices, each of the data acquisition systems obtains data from the receiver based on movement of at least one of the devices with the respect to the other device; and a key generation system that generates one or more keys based on the obtained data from each of the data acquisition systems for use in securing communications between the devices, wherein the one or more keys at each of the devices are substantially the same. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77)
