Near field communication (NFC) enhanced computing systems
Technologies are disclosed herein for utilizing near field communication (“NFC”) to improve the security, performance, and configuration of computing systems. In particular, NFC can be utilized to power an NFC-equipped server computer on or off, to log directly into an operating system executing on the NFC-equipped server computer, to stream firmware debugging data from an NFC-equipped server computer to an NFC-equipped mobile device, to initiate the update or recovery of firmware, to provide hardware inventory data, or to pair hardware devices. Firmware debugging data can also be streamed from a firmware to an NFC-equipped mobile device. NFC can also be utilized to disable functionality provided by a mobile device while the device is in motion, such as when a user of the mobile device is operating a motor vehicle.
1. A computer-implemented method for utilizing near field communication (NFC) to log into an operating system executing on an NFC-equipped computer, the method comprising:
performing a Power-On-Self-Test (POST) operation on the NFC-equipped computer;
determining that credentials have been received at an NFC reader in the NFC-equipped computer during performance of the POST operation;
providing the credentials from the NFC reader directly to a component integrated into a firmware executing in the NFC-equipped computer, the component being configured to receive the credentials from the NFC reader;
executing the operating system on the NFC-equipped computer; and
providing, by the component, the credentials from the firmware directly to a driver executing on the operating system, the driver being integrated into the operating system and configured to utilize the credentials to log a user into the operating system.
2. The computer-implemented method of claim 1 , wherein the firmware comprises a Unified Extensible Firmware Interface (UEFI) Specification—compliant firmware, and wherein the component comprises a UEFI Protocol configured to receive the credentials directly from the NFC reader and to provide the credentials to the driver executing on the operating system.
3. The computer-implemented method of claim 1 , further comprising:
receiving, by the driver, user input from a keyboard connected to the NFC-equipped computer; and
utilizing the credentials and the user input to log the user into the operating system.
4. A headless computer, comprising:
one or more processors;
a near field communication (NFC) reader;
a mass storage device storing an operating system comprising a driver configured to log a user into the operating system; and
a non-volatile memory storing instructions which, when executed on the one or more processors, cause the headless computer to
perform a Power-On-Self-Test (POST) operation on the headless computer;
determine that credentials have been received at the NFC reader during performance of the POST operation;
provide the credentials from the NFC reader directly to component integrated into a firmware executing in the headless computer, the component being configured to receive the credentials from the NFC reader;
boot the operating system on the headless computer after completion of the performance of the POST operation; and
provide, by the component, the credentials from the firmware directly to the driver executing on the operating system, the driver being configured to utilize the credentials to log the user into the operating system.
5. The headless computer of claim 4 , wherein the firmware comprises a Unified Extensible Firmware Interface (UEFI) Specification—compliant firmware, and wherein the component comprises a UEFI Protocol configured to receive the credentials directly from the NFC reader and to provide the credentials to the driver executing on the operating system.
6. The headless computer of claim 4 , wherein the firmware comprises further instructions to: receive, by the driver, user input from a keyboard connected to the headless computer; and utilize the credentials and the user input to log the user into the operating system.
7. A non-transitory computer-readable storage medium having instructions stored thereupon which, when executed by a processor, cause the processor to:
perform a Power-On-Self-Test (POST) operation on a near field communication (NFC)-equipped computer;
determine that credentials have been received at an NFC reader in the NFC-equipped computer during performance of the POST operation;
provide the credentials from the NFC reader directly to a component integrated into a firmware executing in the NFC-equipped computer, the component being configured to receive the credentials from the NFC reader;
boot an operating system on the NFC-equipped computer after completion of the performance of the POST operation; and
provide, by the component, the credentials from the firmware directly to a driver executing on the operating system, the driver being integrated into the operating system and configured to utilize the credentials to log a user into the operating system.
8. The non-transitory computer-readable storage medium of claim 7 , wherein the firmware comprises a Unified Extensible Firmware Interface (UEFI) Specification—compliant firmware, and wherein the component comprises a UEFI Protocol configured to receive the credentials directly from the NFC reader and to provide the credentials to the driver executing on the operating system.
9. The non-transitory computer-readable storage medium of claim 7 , comprising further instructions to: receive, by the driver, user input from a keyboard; and utilize the credentials and the user input to log the user into the operating system.
