Authorized Commands Based on Cryptographic Information

One or more non-transitory computer-readable media comprising computer-executable instructions that, when executed by one or more processors of a first device, cause the first device to perform operations comprising:

• generating, by the first device, during a first time period, first cryptographic information based at least in part on shared data that is shared between the first device and a second device;
• exchanging, by the first device with the second device, the first cryptographic information with second cryptographic information generated by the second device based on the shared data;
• receiving, by the first device from the second device, during a second time period, a broadcast including first information;
• generating, by the first device, a determination that the first information corresponds with the second cryptographic information;
• and
• transmitting, by the first device to the second device, based at least in part on the determination, a command, wherein the command includes second information corresponding with the first cryptographic information.

A first device comprising:

• a memory comprising computer-executable instructions;
• and
• a processor configured to access the memory and execute the computer-executable instructions to perform operations comprising:
• generating, by the first device, during a first time period, first cryptographic information based at least in part on shared data that is shared between the first device and a second device;
• exchanging, by the first device with the second device, the first cryptographic information with second cryptographic information generated by the second device based on the shared data;
• receiving, by the first device from the second device, during a second time period, a broadcast including first information;
• generating, by the first device, a determination that the first information corresponds with the second cryptographic information;
• and
• transmitting, by the first device to the second device, based at least in part on the determination, a command, wherein the command includes second information corresponding with the first cryptographic information.
