Out-Phased Array Linearized Signaling

Data security has always been a major concern, particularly with the surge in online interactions and digital data transmission. Technologies that enable the secure, efficient transmission of data have hence become crucial. Traditional methods of encrypting data focused on software-level defenses, which can be hacked or bypassed, thus emphasizing the need for hardware-level, physical encryption. Current encryption methods often ignore the physical layer of data transmission that can also be susceptible to interference and breaches. Incorporating physical-layer encryption can therefore address an unmet need in secure data communication.

Technology Description

This technology is a system and technique for a physical layer encryption using beamforming to provide secure communications. It utilizes the principle of linear amplification with nonlinear components (LINC) to produce a transmit signal with a limited dynamic range, thus creating a more controlled, secure means of transmission. The key feature of this technology is the generation of a masking signal based on the source data signal to aid in producing a transmit signal with limited dynamic range while ensuring a high degree of secrecy. Unlike traditional encryption techniques, this approach incorporates the actual physical layer in the encryption process to add an additional layer of security. The approach of utilizing beamforming for improved signal strength and reception, paired with the LINC technique that limits the dynamic range of the signal, makes it unique. The generation of a masking signal from the source data also greatly enhances the security of the transmitted information.
