Eavesdropping Attack with Hong-Ou-Mandel Interferometer and Random Basis Shuffling in Quantum Key Distribution

Abstract

We introduce new sophisticated attacks with a Hong-Ou-Mandel interferometer against quantum key distribution (QKD) and propose a new QKD protocol grafted with random basis shuffling to block up those attacks. When the polarization basis is randomly and independently shuffled by sender and receiver, the new protocol can overcome the attacks even for not-so-weak coherent pulses. We estimate the number of photons to guarantee the security of the protocol.

Eavesdropping attack with a Hong-Ou-Mandel interferometer

C. -M. Kim, Y. -W. Kim, Ingyoung Kim +1 more

We introduce a new sophisticated attack with a Hong-Ou-Mandel interferometer against quantum key distribution (QKD) and apply the attack to the QKD protocol with blind polarization. We also discuss how efficient our attack protocol is to ping-pong type protocols.

Quantum Key Distribution with Blind Polarization Bases

Won-Ho Kye, Chil-Min Kim, M. S. Kim +1 more

We propose a new quantum key distribution scheme that uses the blind polarization basis. In our scheme the sender and the receiver share key information by exchanging qubits with arbitrary polarization angles without basis reconciliation. As only random polarizations are transmitted, our protocol is secure even when a key is embedded in a not-so-weak coherent-state pulse. We show its security against the photon-number splitting attack and the impersonation attack.

Secure quantum key distribution with a single not-so-weak coherent pulse

Chil-Min Kim, Yong‐Wan Kim, Young-Jai Park

We propose a secure quantum key distribution (QKD) protocol using a single not-so-weak coherent qubit. With two preprocesses for random rotation and compensation, a key bit is encoded to a randomly polarized not-so-weak coherent qubit. We analyze the security of the QKD protocol, which counters the photon number splitting and the impersonation attacks. The estimated mean number of photon, which is less than 6.0, guarantees security. Additionally, we discuss the possibility of quantum secure direct communication.

Randomized Quantum Key Distribution

Muhammad Sher, Muhammad Musharraf, Thomas Magedanz

By using entangled photon pairs in random polarizations, a protocol that can be used to distribute a quantum key and detect eavesdropping simultaneously is presented. In this scheme, four local unitary operations and the Bell state measurement are used. The non-requirement of classical channel and random selection of polarization basis make this protocol perfectly secure. The stability of this scheme against certain security attacks is also analyzed.

Deterministic quantum key distribution based on random phase coding

Lin Qing-Qun, Wang Fa-Qiang, Mi Jing-Long +3 more

We propose a new quantum key distribution scheme based on random phase coding. In this scheme, the sender and the receiver can share the secret information without basis reconciliation,and besides, this scheme is more efficient. As the phase of the qubit is coded randomly, this protocol is robust even when the source is not a prefect single photon. We show theoretically that it has higher security against the attacks, such as the photon-number-splitting, the impersonation attack, and the Trojan attack, etc., than the previous QKD scheme.

QUANTUM KEY DISTRIBUTION WITH CLASSICAL ALICE

Hua Lu, Qing-yu Cai

It seems that quantum key distribution (QKD) may be completely insecure when the message sender Alice always encodes her key bits in a fixed basis. In this paper, we present a QKD protocol with classical Alice, i.e. Alice always encodes her key bit in the {|0〉,|1〉} basis (we call it classical {0,1} basis) and the eavesdropper Eve knows this fact. We prove that our protocol is completely robust against any eavesdropping attack and present the amount of tolerable noise against Eve's individual attack. Next, we present a QKD protocol to demonstrate that secure key bits can be distributed even if neither Alice nor Bob has quantum capacities, and extend this idea to a QKD network protocol with numerous parties who have only classical capacities. Finally, we discuss that quantum is necessary in QKD for security reasons, but both Alice and Bob may be classical.
