Persona and device based certificate management
View Patent ↗A user device implements a certificate authority for issuing digital certificates that extend to other computing devices a level of trust to a particular user paired with the user device. The user device may obtain user persona information, generate a user key, and combine the user key with a device key for the generation of a digital certificate. The computing device may further transmit the digital certificate to a certificate management system, which manages interactions between other computing devices and the user device or authorizes operation of other computing devices by the particular user based on the digital certificate.
1. A computer implemented certificate management system comprising:
a first electronic data repository storing digital certificates associated with particular user-device pairings;
a second electronic data repository storing reaction policies for computing devices under management of the certificate management system; and
a computer system comprising one or more processors, the computer system configured to at least:
receive a target digital certificate from a target computing device, wherein the target digital certificate certifies a pairing of a target user and the target computing device;
store the target digital certificate in the first electronic data repository;
associate one or more reaction policies with the target digital certificate;
receive a request for a reaction policy from a reacting computing device, wherein the request includes identification information regarding the target computing device and wherein the reacting computing device initiates the request responsive to the reacting computing device detecting the target computing device;
identify the target digital certificate from the first electronic data repository based, at least in part, on the identification information;
obtain the one or more reaction policies associated with the target digital certificate; and
cause the reacting computing device to perform actions in accordance with the one or more reaction policies;
wherein the target digital certificate is issued by a certificate authority implemented on the target computing device; and
wherein the certificate authority resides at the lowest hardware level of the target computing device.
2. The computer implemented certificate management system of claim 1 , wherein the target digital certificate is generated based at least partly on a private key associated with the target user and a public key associated with the target computing device.
3. The computer implemented certificate management system of claim 1 , wherein the pairing of a target user and the target computing device indicates that the target computing device is under control of the target user.
4. The computer implemented certificate management system of claim 1 , wherein associating the one or more reaction policies with the target digital certificate comprises storing the one or more reaction policies in the second electronic repository.
5. The computer implemented certificate management system of claim 1 , wherein the reacting computing device is under management of the certificate management system.
6. The computer implemented certificate management system of claim 1 , wherein the reacting computing device detects the target computing device using a device locating technology.
7. The computer implemented certificate management system of claim 6 , wherein the detection of the target computing device is based at least partly on wireless signals transmitted from the target computing device.
8. The computer implemented certificate management system of claim 6 , wherein the device locating technology is based on GPS, cellular, or other wireless signals.
9. The computer implemented certificate management system of claim 1 , wherein the identification information regarding the target computing device comprises at least one of a MAC address, SSID, or IP address.
10. The computer implemented certificate management system of claim 1 , wherein the computer system is further configured to authorize the reacting computing device to be used or operated by the target user based on the one or more reaction policies.
11. The computer implemented certificate management system of claim 1 , wherein the target computing device and the reacting computing device comprise Internet of Things (IoT) devices.
12. The computer implemented certificate management system of claim 11 , wherein the target computing device and the reacting computing device are remotely located from the computer system.
13. The computer implemented certificate management system of claim 1 , wherein the target computing device and the reacting computing device are remotely located from the computer system.
