Quantum cryptography
Dag Roar Hjelme, Lars Lydersen, Vadim Makarov
This is a chapter on quantum cryptography for the book "A Multidisciplinary Introduction to Information Security" to be published by CRC Press in 2011/2012. The chapter aims to int…
Secure gated detection scheme for quantum cryptography
Lars Lydersen, Vadim Makarov, Johannes Skaar
Several attacks have been proposed on quantum key distribution systems with gated single-photon detectors. The attacks involve triggering the detectors outside the center of the de…
Reply to "Avoiding the Detector Blinding Attack on Quantum Cryptography"
Lars Lydersen, Carlos Wiechers, Christoffer Wittmann +3
This is a reply to the comment by Yuan et al. [arXiv:1009.6130v1] on our publication [arXiv:1008.4593].
Controlling passively-quenched single photon detectors by bright light
Vadim Makarov
Single photon detectors based on passively-quenched avalanche photodiodes can be temporarily blinded by relatively bright light, of intensity less than a nanowatt. I describe a bri…
Faked states attack using detector efficiency mismatch on SARG04, phase-time, DPSK, and Ekert protocols
Vadim Makarov, Johannes Skaar
In quantum cryptosystems, variations in detector efficiency can be exploited to stage a successful attack. This happens when the efficiencies of Bob's two detectors are different f…
Effects of detector efficiency mismatch on security of quantum cryptosystems
Vadim Makarov, Andrey Anisimov, Johannes Skaar
We suggest a type of attack on quantum cryptosystems that exploits variations in detector efficiency as a function of a control parameter accessible to an eavesdropper. With gated…
