Random numbers are a fundamental resource in science and engineering with important
applications in simulation and cryptography. The inherent randomness at the core of …

Communication security has to evolve to a higher plane in the face of the threat from the
massive computing power of the emerging quantum computers. Quantum secure direct …

Random numbers are central to cryptography and various other tasks. The intrinsic
probabilistic nature of quantum mechanics has allowed us to construct a large number of …

Cryptography is the study and practice of secure communication with digital data and
focuses on confidentiality, integrity, and authentication. Random number generators (RNGs) …

To remove any trusted third party from the voting scheme, a new primitive quantum secure
multiparty exclusive OR protocol based on Measurement-Device-Independence (MDI) is …

Quantum random numbers have an incomparable advantage over pseudo-random numbers
since randomness originates from intrinsic property of quantum mechanics. The generation …

Range query in cloud-based outsourcing applications is an important data search service,
but it can suffer from privacy disclosure. In this paper, we generalize and redefine privacy …

We report an experimental realisation of a quantum random number generator using a
plasmonic beamsplitter. Free-space single photons are converted into propagating single …

Truly random numbers are in great demand in various applications. Self-testing quantum
random number generators provide a way to verify that random numbers indeed come from …

Nowadays, data transfer has been vast online and on social media. Hence data security in
the various cloud environments has been enabled to send and receive data. While …
