| Towards genuine randomness in the presence of experimental imperfections | QCRYPT 2024 | — |
The generation of random numbers has an essential role in cryptography, with most practical applications still relying on Pseudo Random Number Generators (PRNGs). However, strings generated by PRNGs are always computable, representing a fatal flaw for their use in cryptographic protocols. For this reason, we designed a QRNG protocol that generates maximally unpredictable strings by localising value indefiniteness, therefore having a provable advantage over any PRNG. Moreover, a photonic implementation without the need for entanglement is possible for this approach, making it suitable for practical applications. However, the role of errors in an operational photonic embodiment is yet to be fully understood. Thus, this work aims to start the development of an error analysis framework to guarantee incomputability even in the presence of experimental imperfections. |
