Security in quantum cryptography
Reviews of Modern Physics, 2022 Quantum cryptography exploits principles of quantum physics for the secure processing of information. A prominent example is secure communication, i.e., the task of transmitting confidential messages from one location to another. The cryptographic requirement here is that the transmitted messages remain inaccessible to anyone other than the designated ...

Unconditional security in quantum cryptography [PDF]
Journal of the ACM, 2001 Basic techniques to prove the unconditional security of quantum crypto graphy are described. They are applied to a quantum key distribution protocol proposed by Bennett and Brassard [1984]. The proof considers a practical variation on the protocol in which the channel is noisy and photos may be lost during the transmission.

A Higher-Level Security Scheme for Key Access on Cloud Computing
IEEE Access, 2021 In this work, we construct a key access management scheme that seamlessly transitions any hierarchical-like access policy to the digital medium. The proposed scheme allows any public cloud system to be used as a private cloud.

Secure Auctions without Cryptography [PDF]
, 2014 An auction is a simple way of selling and buying goods. Modern auction protocols often rely on complex cryptographic operations to ensure manifold security properties such as bidder-anonymity or bid-privacy, non-repudiation, fairness or public verifiability of the result.

Harden Deep Convolutional Classifiers via K-Means Reconstruction
IEEE Access, 2020 Adversarial examples are carefully perturbed input examples that aim to mislead the deep neural network models into producing unexpected outputs. In this paper, we employ a K-means clustering algorithm as a pre-processing method to defend against ...
