Abstract
Secure communication for autonomous vehicles can be increased by performing authentication operations before nodes, such as vehicles, roadside equipment (RSE), or base stations, are within communications range. A digital certificate management system for mobile nodes, including for moving vehicles, can facilitate ultra fast communications between vehicles and other nodes. The RSE can propagate vehicle node data, comprising direction, speed, or estimated time of arrival, to other vehicles and/or other RSEs. Consequently, this propagation of data prior to the communication between nodes can facilitate an efficient authentication system.
Claims20
A method, comprising:
- in response to receiving a first encryption key from a mobile device, generating, by a first node device comprising a processor, estimation data representative of an estimate of a direction of travel of the mobile device, wherein the estimation data is based on the direction of travel of the mobile device in relation to a geometry associated with a street via which the mobile device is traveling, and wherein the first encryption key facilitates first authentication applicable to establishing a first secured wireless connection between the mobile device and the first node device;
- and
- based on the estimation data, transmitting, by the first node device, a second encryption key to a second node device prior to the mobile device being within a wireless connection distance of the second node device, wherein the second encryption key facilitates second authentication applicable to establishing a second secured wireless connection between the mobile device and the second node device.
A first node device, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- in response to receiving a first encryption key from a mobile device, generating prediction data representative of a prediction of a second direction of the mobile device, wherein the prediction data is based on a first direction of the mobile device in relation to a geometry associated with a road via which the mobile device is traveling, and wherein the first encryption key facilitates a first authentication to enable a first secured network connection to be established between the mobile device and the first node device;
- and
- based on the prediction data, transmitting a second encryption key to a second node device prior to the mobile device being within a network connection distance of the second node device to facilitate a second authentication to enable a second secured network connection to be established between the mobile device and the second node device.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of first node equipment, facilitate performance of operations, comprising:
- in response to receiving a first encryption key from a user equipment, determining estimation information representative of an estimate of a direction of travel of the user equipment, wherein the estimation information is based on the direction of travel of the user equipment in relation to a geometry associated with a route via which the user equipment is traveling, and wherein the first encryption key facilitates a first authentication for establishment of a first secured wireless connection between the user equipment and the first node equipment;
- and
- based on the estimation information, communicating a second encryption key to second node equipment prior to the user equipment being within a wireless connection distance of the second node equipment, wherein the second encryption key facilitates a second authentication for establishment of a second secured wireless connection between the user equipment and the second node equipment, and wherein the second encryption key is different from the first encryption key.
