  • Publication number: 20240078539
    Abstract: A computer-implemented method, in accordance with one embodiment, includes receiving, at an offline input bridge module, a transaction order and a corresponding cryptogram. The transaction order and the cryptogram are transferred from the input bridge module to a disconnected vault module. The input bridge module is discarded in response to the transfer of the transaction order and cryptogram. The transaction order is converted to an unsigned transaction, using the disconnected vault module. The unsigned transaction and cryptogram are transferred to an offline hardware security module. A seed is unwrapped from the cryptogram, using the hardware security module. A key for signing the transaction is generated, using the hardware security module. The signed transaction is transferred to an offline output bridge module, and from the output bridge module to an online module. The output bridge module is discarded in response to the transfer of the signed transaction and the cryptogram therefrom.
