  • Patent number: 12651241
    Abstract: Systems and methods involving secure connections between security meshes are disclosed herein. One disclosed device includes a first security processor located within a first security mesh, a first casing having a connector and supporting the first security mesh and the applications processor, a second security processor located within a second security mesh, and a second casing connected to the first casing via the connector and supporting the second security mesh. The first security processor and second security processor are programmed to generate a unique pre-shared key independently on both the first security processor and the second security processor using an elliptic key exchange and establish a secure connection between the first security processor and the second security processor using the unique pre-shared key.
    Type: Grant

  • Publication number: 20240291564
    Abstract: Systems and methods for forming a verified secure wireless connection are disclosed. One system includes a first device with a first transceiver and a second device with a second transceiver. The second device does not include a display or any other means for providing high resolution visible light information. The system also includes a visible light signal source on the second device. The first and second devices store computer-readable instructions to initialize a secure wireless connection using the first transceiver and the second transceiver. The second device also stores computer-readable instructions to generate a visible light signal using the visible light source. The first device stores computer-readable instructions to verify the secure wireless connection using the visible light signal.
