A method to securely communicate a shared key to a first device comprising a boot device and a second device comprising a central processor configured to be communicatively coupled via a data bus, comprising: receiving, by the first device, a shared key and unique identifier pairing associated with the first device from a key generator; receiving, by a trusted third party, the shared key and unique identifier pairing from the key generator; generating, by the first device, a signature using the unique identifier and the shared key; transmitting, by the first device, the signature and the unique identifier to the trusted third party, wherein the trusted third party is communicatively coupled to the central processor via a network; verifying, by the trusted third party, the unique identifier based on the signature; determining, by the trusted third party, the shared key when the unique identifier is verified; and transmitting, by the trusted third party, the shared key to the second device to enable the first device and the second device to communicate securely by encoding and decoding communicated data using the shared key comprising: signing, by the boot device, startup routine instructions stored in the boot device by encoding the startup routine instructions using the shared key; transmitting, by the boot device, the signed startup routine instructions to the central processor; verifying, by the central processor, the signed startup routine instructions by decoding the signed startup routine instructions using the shared key; and executing, by the central processor, the startup routine instructions to initialize a computing system. receiving, by the first device, a shared key and unique identifier pairing associated with the first device from a key generator; receiving, by a trusted third party, the shared key and unique identifier pairing from the key generator; generating, by the first device, a signature using the unique identifier and the shared key; transmitting, by the first device, the signature and the unique identifier to the trusted third party, wherein the trusted third party is communicatively coupled to the central processor via a network; verifying, by the trusted third party, the unique identifier based on the signature; determining, by the trusted third party, the shared key when the unique identifier is verified; and transmitting, by the trusted third party, the shared key to the second device to enable the first device and the second device to communicate securely by encoding and decoding communicated data using the shared key comprising: signing, by the boot device, startup routine instructions stored in the boot device by encoding the startup routine instructions using the shared key; transmitting, by the boot device, the signed startup routine instructions to the central processor; verifying, by the central processor, the signed startup routine instructions by decoding the signed startup routine instructions using the shared key; and executing, by the central processor, the startup routine instructions to initialize a computing system. signing, by the boot device, startup routine instructions stored in the boot device by encoding the startup routine instructions using the shared key; transmitting, by the boot device, the signed startup routine instructions to the central processor; verifying, by the central processor, the signed startup routine instructions by decoding the signed startup routine instructions using the shared key; and executing, by the central processor, the startup routine instructions to initialize a computing system.
