Polar Coding for Physical-layer Security without Knowledge of the Eavesdropper's Channel ID: 2019-021

An innovative approach to enhance wireless communication security using polar codes without requiring knowledge of the eavesdropper's channel condition.

Technology Overview

This technology employs polar coding to provide an additional layer of security in wireless communication systems. It uniquely generates a random sequence per message, improving the reliability for the legitimate receiver while obfuscating the message for any potential eavesdroppers, without compromising the receiver's performance. The method is distinct in its lack of reliance on the signal-to-noise ratio for message bit selection during encoding, making it robust against eavesdroppers with potentially superior channel conditions.

Key Advantages

• Enhances security without knowledge of the eavesdropper's channel condition
• Does not degrade the legitimate receiver's performance
• Lacks dependence on signal-to-noise ratio for encoding, increasing robustness
• Applicable in both wireless and wired communication scenarios

Problems Addressed

• Improves security in environments where the eavesdropper's channel condition is unknown
• Eliminates the need for signal-to-noise ratio consideration in secure message transmission
• Prevents degradation of legitimate receiver's performance due to security measures

Market Applications

• Secure point-to-point communications for telecommunications companies
• Enhanced security protocols for wireless and wired communication systems
• Security solutions for applications requiring high reliability and confidentiality
