Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 6:
7. A non-transitory computer readable medium comprising one or more instructions that when executed by a processor of a transport cause the processor to perform:
detecting an action performed by a component of the transport utilizing a component of transport;
generating a random seed based on the action;
receiving information associated with the action from the component;
generating, by the transport, a cryptographic key based on the random seed: wherein the cryptographic key is generated based on any one of: powering of the transport, passing of a threshold time period, or detection of another action utilizing any of transport components;
transmitting the cryptographic key to a remote server;
receiving consent for changing the cryptographic key, wherein the consent constitutes a blockchain consensus,
executing a smart contract to record the cryptographic key and timestamp of the key generation on a blockchain;
receiving, from the remote server, a software update for a system installed within the transport, wherein the software update is signed with the cryptographic key; and
installing the software update within the system based on a verification that the corresponds to the cryptographic key.
