Quantum cryptography could be useful to strengthen the security around the breaches that were exploited for these attacks. Properties such as non-repudiation, i.e. the impossibility for a bank to deny having sent a message received by another bank, can be found in quantum digital signatures, and quantum tokens could be used for a better tracing of messages.

In this case, the assets that are moving between banks represent money. For this reason, a quantum SWIFT system based on quantum money and quantum digital signatures could offer very high security guarantees.
