Abstract
Securing protocol keys in a communication node comprises transferring a protocol access key stored in a secure enclave of a secure host platform to a secure key store in a communication platform via a secure transfer. The protocol access key which is plaintext is secure from access by a host processor of the secure host platform. A protocol key stored in the secure enclave is encrypted to an encrypted protocol key. The encrypted protocol key is transferred from the secure enclave to the communication platform over an unsecure bus. The encrypted protocol key is deciphered based on the protocol access key in the communication platform to form the protocol key. The protocol key which is plaintext is secured from access by the host processor, the communication controller, or both.
