A method may include: generating, by a plurality of auditor computer programs and a data curator computer program, a first random string using a first distributed randomness protocol; sending the first random string to a quantum party computer program; executing, by the quantum party computer program, a certified randomness protocol with a quantum randomness source using the first random string; receiving, from the quantum randomness source, a first quantum randomness; generating, by the auditor computer programs and the data curator computer program, a second random string using a second distributed randomness protocol; extracting, by the data curator computer program and using a randomness extractor, a second quantum randomness from the first quantum randomness using the second random string, wherein the second quantum randomness comprises a near-uniformly random string; and executing, by the data curator computer program, a differential privacy protocol using the second quantum randomness as additive noise.

Systems and methods for secure cryptographic secret distribution are disclosed. In one embodiment, a method for secure cryptographic secret distribution may include: (1) receiving, at a key relay station, a cryptographic secret from a webserver over a first communication network; (2) storing, by the key relay station, the cryptographic secret; (3) authenticating, by the key relay station, an end user via an end user electronic device; and (4) securely communicating, by the key relay station, the cryptographic secret to the end user electronic device. The end user electronic device is configured to store the cryptographic secret in secure storage on the end user electronic device, to encrypt data with the cryptographic secret, and to communicate the encrypted data to the webserver over a second communication network.

A method may include: sharing, by a client computer program and a server computer program, a set of identification keys, each identification key associated with a key label, and an authentication key; selecting, by the client computer program and the server computer program, one of the key labels; preparing, by the client computer program, quantum systems using a basis, randomly chosen bit values, and intensities; sending, by the client computer program, the quantum systems to the server computer program over a quantum communication channel, wherein the server computer program may be configured to measure the quantum systems using the basis and to announce quantum systems with photon detection; and generating, by the client computer program, a client tag using a shared keyed hash function executed on the authentication key and chosen bit values from the quantum systems with photon detection, and forwarding the client tag to the server computer program.
