Title:
METHOD AND SYSTEM FOR OCDM-BASED PHOTONIC LAYER SECURITY ROBUSTNESS TO SPOOF DATA INTEGRITY
Document Type and Number:
WIPO Patent Application WO/2010/039309
Kind Code:
A3
Abstract:
A system and method is provided for identifying fraudulent data in an optical data transmission. The system and method includes scrambling an encoded data signal using dynamically changing scramble code; transmitting the scrambled encoded data signal over a network; descrambling the scrambled encoded data signal using a descramble code corresponding to a compliment of the dynamically changing scramble code; analyzing the descrambled encoded data signal to search for a region of low error between descrambled data and noise; notifying of a possible spoofing attempt when a region of low error is not found; and decoding the descrambled encoded data signal using a compliment of phase codes originally used for encoding the encoded data signal in order to generate a decoded signal to retrieve a desired data signal when a region of low error is found.
