Flexible quantum private queries based on quantum key distribution

open access: yes, 2011
We present a flexible quantum-key-distribution-based protocol for quantum private queries. Similar to M. Jakobi et al's protocol [Phys. Rev. A 83, 022301 (2011)], it is loss tolerant, practical and robust against quantum memory attack.

Private Key and Group Key Generation Using Correlated Sources and Wiretap Broadcast Channel in Presence of One-Way Public Communication

open access: yesIEEE Access, 2019
Encryption with shared key is one of the methods to ensure secure communication. To meet the requirements of keys, this paper investigates the problem of generating private key (PK) and group key (GK) using correlated sources and discrete memoryless ...

A Private Key Management Scheme on Blockchain Against Collusion Attacks [PDF]

open access: yesJisuanji gongcheng, 2020
To address the security of the recovery of lost private keys on the blockchain,this paper proposes a distributed management scheme for private keys based on threshold secret sharing.The scheme combines the user’s private key with the secret password as a

General paradigm for distilling classical key from quantum states

open access: yes, 2008
We develop a formalism for distilling a classical key from a quantum state in a systematic way, expanding on our previous work on secure key from bound entanglement [K. Horodecki et. al., Phys. Rev. Lett. 94 (2005)].

Efficient Quantum Private Comparison without Sharing a Key

open access: yesEntropy, 2023
Quantum private comparison (QPC) allows at least two users to compare the equality of their secret information, for which the security is based on the properties of quantum mechanics.

A New Secret key Agreement Scheme in a Four-Terminal Network

open access: yes, 2011
A new scenario for generating a secret key and two private keys among three Terminals in the presence of an external eavesdropper is considered. Terminals 1, 2 and 3 intend to share a common secret key concealed from the external eavesdropper (Terminal 4)

A Simple, Accurate and Highly Secure Method to Encrypt-Decrypt Digital Images

open access: yesJOIV: International Journal on Informatics Visualization, 2019
The digital image may be important and has a secret character, which requires not understanding it when looking at the naked eye or not understanding the contents. So seeking a method of digital image encryption-decryption is a very important task.

A new code‐based digital signature based on the McEliece cryptosystem

open access: yesIET Communications, 2023
Digital signature schemes are used for the authentication and verification of signatures. The Courtois–Finiasz–Sendrier (CFS) digital signature is a well‐known code‐based digital signature scheme based on the Niederreiter cryptosystem. However, it is not
