Method and apparatus for enhancing security of wireless communications
First Claim
1. A method for enhancing security of a communication transmitted by a communicating device, the method comprising:
- providing a cross-layer watermarking unit in the communicating device, the cross-layer watermarking unit comprising at least one of layer-2/3, layer-1 and layer-0;
generating a token/key for watermarking;
transmitting user data while embedding the token/key into the user data transmission at one or more of the layers selectively in accordance with a security policy; and
authenticating the user data with the token/key embedded into the user data transmission.

Abstract
The present invention is related to a method and apparatus for enhancing security of communications. The apparatus comprises a security processing unit, a data processing unit, a cross-layer watermarking unit, and optionally a smart antenna processor. The security processing unit generates a token/key to be used in watermarking and sends a node security policy to other components. The data processing unit generates user data. The cross-layer watermarking unit includes at least one of Layer-2/3, Layer-1 and Layer-0. Each layer performs a different scheme or degree of watermarking. The cross-layer watermarking unit embeds the token/key into the user data transmission on at least one of the layers selectively in accordance with a security policy.
