Patent ID: 10461940

Abstract:
The Secure Firmware Transaction Signing Platform Apparatuses, Methods and Systems (“SFTSP”) transforms transaction signing request inputs via SFTSP components into transaction signing response outputs. A transaction signing request message for a transaction may be received at a first HSM. An encrypted master private key associated with the transaction may be obtained from a second HSM. A private key decryption key associated with the first HSM may be retrieved from the first HSM's tamper-proof storage. The encrypted master private key may be decrypted using the private key decryption key. A transaction hash and a keychain path associated with the transaction signing request message may be determined. A signing private key for the keychain path may be generated by the first HSM using the decrypted master private key. The transaction hash may be signed by the first HSM using the signing private key, and the generated signature may be returned.
