Title of Invention | A METHOD FOR ENHANCING THE SECURITY OF ENCRYPTED TRANSMISSION OF INFORMATION IN A NETWORK COMMUNICATION SYSTEM |
---|---|
Abstract | A Method and Apparatus for a Security System for Wireless Networks is described. The technique involves encryption and decryption at the Physical layer. It also develops a criterion for choosing the encryption/decryption methodology for a particular embodiment for communication systems typically using a Viterbi Decoder and describes how the difficult-to-invert property of the Viterbi Decoder can be utilized to provide security against known-plaintext attacks. Some candidate encryption/decryption methodologies satisfying the developed criterion are also discussed. |
