PAGE TITLE
Overview
PAGE SUMMARY
This invention is a technique for securing wireless communication between a transmitter and receiver by obfuscating the preamble data of the baseband signal at the physical layer. The obfuscation is achieved using unique obfuscation keys generated independently at the transmitter and receiver based on their reciprocal channel characteristics. This method aims to prevent eavesdropping, reactive jamming, and other malicious attacks on wireless transmissions.
ADVANTAGES
TITLE:Key Advantages
Enhanced Security: The technique provides an additional layer of security by obfuscating the preamble data, making it difficult for attackers to intercept and decode transmitted packets
Minimal Overhead: The implementation of this technique requires minimal additional hardware resources, making it cost-effective
Protection Against Reactive Attacks: The method prevents intruders from performing narrow-band reactive jamming and eavesdropping attacks, even if they have access to unlimited power and time
Unique Key Generation: Obfuscation keys are unique and independently generated at the transmitter and receiver, ensuring secure communication
Flexibility: The technique can support multiple modulation schemes, multiple access techniques, and multiple antenna configurations
Problem Solved
TITLE:Problems Solved
Eavesdropping: The technique addresses the problem of malicious eavesdropping by securing wireless transmissions through physical layer obfuscation
