Seed splitting and firmware extension for secure cryptocurrency key backup, restore, and transaction signing platform apparatuses, methods and systems |
| abstract |
The Seed Splitting and Firmware Extension for Secure Cryptocurrency Key Backup, Restore, and Transaction Signing Platform Apparatuses, Methods and Systems (“SFTSP”) transforms transaction signing request, key backup request, key recovery request inputs via SFTSP components into transaction signing response, key backup response, key recovery response outputs. A transaction signing request message for a transaction is received by a first HSM and includes an encrypted second master key share from a second HSM whose access is controlled by M-of-N authentication policy. The encrypted second master key share is decrypted. A first master key share is retrieved. A master private key is recovered from the master key shares. A transaction hash and a keychain path is determined. A signing private key for the keychain path is generated using the recovered master private key. The transaction hash is signed using the signing private key, and the generated signature is returned. |
