Quantum computer: The ‘coronavirus’ of cryptographyQuantum-resistant cryptography or post-quantum cryptography develops cryptographic systems that are secure and able to protect existing communications protocols and networks from attacks from large-scale quantum and classical computers. Quantum cryptography Quantum cryptography, on the other hand, is a protocol for transmission of data. It offers new encryption through quantum key distribution (QKD), which will assure secure communication in a quantum computer era but the solution must also fit economically with business processes. With post-quantum cryptography, algorithms can be applied in the same places as current cryptography. Instead, a much simpler quantum computer can be used for things that are very likely to become popular and well known, such as medicine and chemistry research. For the payments industry, it is important to be prepared and remember that early payment systems used classic cryptography systems for keeping our transaction systems running. For example, the NewHope algorithm for post-quantum key exchange is already applied by Google for interested users and works inside TLS without you noticing at all.
