Security of the private quantum channel

چکیده

We extensively discuss the problem of encryption of quantum information. We present an attack on the private quantum channel which applies when partial classical description of the cipher text is known (the known-ciphertext attack) and show how to avoid this situation. The quantum analogue of the known-plaintext attack is also discussed.

Side-channel free quantum key distribution by Samuel L. Braunstein and Stefano Pirandola IN DEFENSE OF PRIVATE SPACES

In quantum cryptography unconditional security proofs are derived under the assumption that Alice's and Bob's apparata (private spaces) are completely inaccessible by an eavesdropper who, therefore, can only attack the signal systems which are transmitted through the quantum communication channel connecting the two parties. Under this assumption, secret-key rates and security thresholds are der...

On the Security of O-PSI a Delegated Private Set Intersection on Outsourced Datasets (Extended Version)

In recent years, determining the common information privately and efficiently between two mutually mistrusting parties have become an important issue in social networks. Many Private set intersection (PSI) protocols have been introduced to address this issue. By applying these protocols, two parties can compute the intersection between their sets without disclosing any information about compone...

Decoherence effects on quantum Fisher information of multi-qubit W states

Quantum fisher information of a parameter characterizing the sensitivity of a state with respect to parameter changes. In this paper, we study the quantum fisher information of the W state for four, five, six and seven particles in decoherence channels, such as amplitude damping, phase damping and depolarizing channel. Using Krauss operators for decoherence channels components, we investigate t...

Teleportation via an Entangled Coherent Channel and Decoherence Effect on This Channel

We study an entangled two-mode coherent state within the framework of2×2-dimensional Hilbert space. We investigate the problem of quantum teleportation ofa superposition coherent state via an entangled coherent channel. By three differentmeasures with the titles ``minimum assured fidelity (MASF)”, ``average teleportationfidelity” and ``optimal fidelity (f)” we study the ...

Quantum Blind Signature with an Offline Repository

We propose a quantum blind signature scheme that achieves perfect security under the assumption of an honest offline repository. The security of the protocol also relies on perfect private quantum channels, which are achievable using quantum one-time pads with keys shared via a QKD protocol. The proposed approach ensures that signatures cannot be copied and that the sender must compromise to a ...
