Patent Primary Examiner
An example method includes receiving a quantum-resistant double signature (QSDS) message. The QSDS message is generated by digitally signing a quantum SignerInfo (qSignerInfo) attribute of a Quantum Signed Data (QSignedData) message using a private key of a signing party computing system using a quantum-vulnerable signature algorithm. The method then includes verifying the digital signature on the QSDS message, identifying the qSignerInfo attribute in a SignedAttributes value of the QSDS message, transmitting the SignedAttributes value to a QSDS processing computing system, and receiving, from the QSDS processing computing system, a verification notification for the QSignedData message.
