In one embodiment, a method is disclosed comprising scanning a network to obtain a list of devices on the network; classifying the devices as either controlled, uncontrolled or restricted devices; establishing a secure channel with the controlled devices; issuing one or more control commands to the controlled devices over the secure channel, the one or more control commands included within a signed message, the signed message signed using a private key of the sender and verified using a public key of the receiver, the private key and public key generated during the establishing of the secure channel; receiving a response to the control commands; and logging the control commands and the response in a blockchain. ## Claims ### Claim 1 A method comprising: issuing a control command to a vehicle over a channel, the control command causing the vehicle to perform an action; receiving a response to the control command; and logging the response in a blockchain. ### Claim 2 (depends on 1) The method of claim 1, wherein the control command is generated using a Device Identify Composition Engine-Robust Internet of Things (DICE-RIOT) key generation procedure. ### Claim 3 (depends on 1) The method of claim 1, further comprising scanning a network to obtain a list of vehicles on the network, the list of vehicles including the vehicle. ### Claim 4 (depends on 1) The method of claim 1, further comprising establishing the channel by transmitting a triple to the vehicle, the triple including a device identifier, certificate, and public key. ### Claim 5 (depends on 1) The method of claim 1, wherein the control command causes the vehicle to power off. ### Claim 6 (depends on 1) The method of claim 1, further comprising transmitting a notification to uncontrolled vehicles instructing the uncontrolled vehicles to perform an operation. ### Claim 7 (depends on 1) The method of claim 1, wherein logging the response in the blockchain comprises logging a triple of a vehicle generating the control command, a destination public identifier, order information, and a digital signature. ### Claim 8 A non-transitory computer-readable storage medium for tangibly storing computer program instructions capable of being executed by a computer processor, the computer program instructions defining steps of: issuing a control command to a vehicle over a channel, the control command causing the vehicle to perform an action; receiving a response to the control command; and logging the response in a blockchain. ### Claim 9 (depends on 8) The non-transitory computer-readable storage medium of claim 8, wherein the control command is generated using a Device Identify Composition Engine-Robust Internet of Things (DICE-RIOT) key generation procedure. ### Claim 10 (depends on 8) The non-transitory computer-readable storage medium of claim 8, further comprising scanning a network to obtain a list of vehicles on the network, the list of vehicles including the vehicle. ### Claim 11 (depends on 8) The non-transitory computer-readable storage medium of claim 8, the steps further comprising establishing the channel by transmitting a triple to the vehicle, the triple including a device identifier, certificate, and public key. ### Claim 12 (depends on 8) The non-transitory computer-readable storage medium of claim 8, wherein the control command causes the vehicle to power off. ### Claim 13 (depends on 8) The non-transitory computer-readable storage medium of claim 8, further comprising transmitting a notification to uncontrolled vehicles instructing the uncontrolled vehicles to perform an operation. ### Claim 14 (depends on 8) The non-transitory computer-readable storage medium of claim 8, wherein logging the response in the blockchain comprises logging a triple of a vehicle generating the control command, a destination public identifier, order information, and a digital signature. ### Claim 15 A device comprising: a memory; and a processor configured to: issue a control command to a vehicle over a channel, the control command causing the vehicle to perform an action; receive a response to the control command; and log the response in a blockchain. ### Claim 16 (depends on 15) The device of claim 15, further comprising scanning a network to obtain a list of vehicles on the network, the list of vehicles including the vehicle. ### Claim 17 (depends on 15) The device of claim 15, the processor further configured to establish the channel by transmitting a triple to the vehicle, the triple including a device identifier, certificate, and public key. ### Claim 18 (depends on 15) The device of claim 15, wherein the control command causes the vehicle to power off. ### Claim 19 (depends on 15) The device of claim 15, further comprising transmitting a notification to uncontrolled vehicles instructing the uncontrolled vehicles to perform an operation. ### Claim 20 (depends on 15) The device of claim 15, wherein logging the response in the blockchain comprising logging a triple of a vehicle generating the control command, a destination public identifier, order information, and a digital signature.
