Secure wireless connection verification using visible light signals
The patent US12015442B2 describes a system designed to establish a secure wireless connection between two devices, specifically a first device (such as a payment terminal) and a second device (like a mobile device). The system utilizes computer-readable instructions executed by processors to initialize the connection through a series of steps. These include generating a random number, creating a shared secret by combining this random number with a public value from the second device, and encoding the shared secret into a visible light signal. The first device then generates a pattern of light-emitting diode (LED) colors based on this signal, which is compared to a corresponding pattern displayed on the second device to verify the security of the connection.
Further claims in the patent detail additional functionalities, such as the generation and transmission of a public value from the first device to the second, and the use of a Diffie-Hellman key exchange method for creating the shared secret. The system is versatile, allowing for various types of wireless connections, including radio frequency, infrared, or ultraviolet light. The verification process is contingent upon the matching of LED color patterns between the two devices, ensuring that the connection is secure before any data exchange occurs. This innovative approach enhances the security of wireless communications, particularly in sensitive applications like payment processing.
