Classification: CPC H  G | IPC G  H

Claim 3:
4. A system, comprising:
a transport comprising a processor that when executing one or more instructions stored in an associated memory is configured to:
detect an action performed by a component of the transport using a component of the transport;
generate a random seed based on the action;
receive information associated with the action from the component;
generate a cryptographic key based on the random seed, wherein the cryptographic key is generated based on an one of: a powering on of the transport, an expiration of a threshold time period, or detection of another action performed by the transport;
transmit the cryptographic key to a remote server,
receive, a consent to change the cryptographic key, wherein the consent constitutes a blockchain consensus;
execute a smart contract to record the cryptographic key and timestamp of the key generation on a blockchain;
receive, 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
install the software update within the system based on a verification that the key, corresponds to the cryptographic key.
