The purpose of the RBC engine, driven by the server, is to generate matching responses to the ones generated by the PUFs and extract the exact same cryptographic key. The secure server driving the network manages the differences between the PUF responses and the original PUF challenges. In turn, the client devices do not need error correction schemes that match the challenges stored by the server. As a result of the protocol, both the server and the client devices independently generate the same uncorrected PUF responses.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Additional information<\/h2>\n\n\n\n<section  \n    class=\"nau-block nau-block-panels   \" \n    data-layout_mobile=\"groupLayout-Stack gutter_Default panelLayoutPhotoTextVertical  photoAspect-1-1\"\n        data-layout_tablet=\"groupLayout-Stack gutter_Default panelLayoutPhotoTextVertical  photoAspect-1-1\"\n        data-layout_desktop=\"groupLayout-Tabs gutter_Default panelLayoutPhotoTextVertical  photoAspect-1-1\"\n        data-layout_xl=\"groupLayout-Tabs gutter_Default panelLayoutPhotoTextVertical  photoAspect-1-1\">\n\n    <div class=\"background-wrapper\">\n        <div class=\"block-main-content\">\n            \n            \n                            <div class=\"tab-nav\" role=\"tablist\" aria-label=\"Tabs for  articles\">\n                                                \n                        <button data-panel=\"panel--0\"\n                            role=\"tab\"\n                            aria-controls=\"panel--0\"\n                            class=\"active bg-true-blue bg-none\"\n                            tabindex=\"0\">Patent number and inventor<\/button>\n                                                \n                        <button data-panel=\"panel--1\"\n                            role=\"tab\"\n                            aria-controls=\"panel--1\"\n                            class=\"after-active bg-true-blue bg-none\"\n                            tabindex=\"-1\">Potential applications<\/button>\n                                                \n                        <button data-panel=\"panel--2\"\n                            role=\"tab\"\n                            aria-controls=\"panel--2\"\n                            class=\" bg-true-blue bg-none\"\n                            tabindex=\"-1\">Benefits and advantages<\/button>\n                                                \n                        <button data-panel=\"panel--3\"\n                            role=\"tab\"\n                            aria-controls=\"panel--3\"\n                            class=\" bg-true-blue bg-none\"\n                            tabindex=\"-1\">Case number and licensing status<\/button>\n                                    <\/div>\n            \n            \n            \n            <div class=\"panel-wrapper\">\n                \n                                \n                        <div class=\"panel bg-true-blue  panelTypeText  noHover \"\n                            data-role=\"tabpanel\"\n                            data-panel=\"panel--0\"\n                            id=\"panel--0\">\n\n                            \n                                                                    <div class=\"content\">\n                                            <div class=\"text-wrapper\">\n                                                                                                <h3 class=\"h3-tab-index\">Patent number and inventor<\/h3>\n                                                \n                                                                                                    <div class=\"text\">\n                                                        <p>16\/598,985<\/p>\n<p>Bertrand Cambou, Christopher Philabaum, and Dennis D.
