Hashed Strings for Machine-to-Machine Communication Based on Time and Secret Strings

A network device comprising:

• a communication interface;
• one or more memories that store instructions;
• and
• one or more processors to execute the instructions to:
• receive, via the communication interface, a request to invoke a machine-to-machine communication to permit remote control of a vehicle, wherein the request includes a vehicle string that identifies the vehicle and one or more secret strings;
• generate one or more hashed strings based on the vehicle string, the one or more secret strings, and a current time;
• and
• transmit a remote control request to the vehicle, wherein the remote control request includes the one or more hashed strings.

A non-transitory storage medium storing instructions executable by a computational device to:

• receive a request to invoke a machine-to-machine communication to permit remote control of a device, wherein the request includes a device string that identifies the device and one or more secret strings;
• generate one or more hashed strings based on the one or more secret strings, the device string, and a current time;
• and
• generate a remote control request that includes the one or more hashed strings.

A method comprising:

• receiving a request to invoke a machine-to-machine communication to permit remote control of a device, wherein the request includes a device string that identifies the device and one or more secret strings, wherein the one or more secret strings include an action string that indicates an action to be remotely performed by the device;
• generating one or more hashed strings based on the device string, the one or more secret strings, and a current time;
• and
• transmitting a remote control request to the device, wherein the remote control request includes the one or more hashed strings and the one or more secret strings.
