Abstract

Exemplary embodiments of methods and apparatuses to provide shielding from key cracking in wireless networks are described. In one embodiment, a first frame having a first content is identified. Determination is made whether the first frame needs to be shielded. A second frame having at least a portion of the first content is transmitted in response to determining that the first frame needs to be shielded. The first frame has data encrypted with a first encryption and the second frame has data encrypted with a second encryption.
