  • Double Blinding-Attack on Entanglement-Based Quantum Key Distribution Protocols
  • 2012
  • Ingår i: AIP Conference Proceedings. - : AIP. - 0094-243X .- 1551-7616. - 9780735410046 ; 1424:1, s. 9-16
  • Tidskriftsartikel (refereegranskat)abstract
    • We propose a double blinding-attack on entangled-based quantum key distribution protocols. The principle of the attack is the same as in existing blinding attack except that instead of blinding the detectors on one side only, Eve is blinding the detectors of both Alice and Bob. In the BBM92 protocol, the attack allows Eve to get a full knowledge of the key and remain undetected even if Alice and Bob are using 100% efficient detectors. The attack can be easily extended to Ekert protocol, with an efficiency as high as 85.3%.

  • Multiple-photon absorption attack on entanglement-based quantum key distribution protocols
  • 2013
  • Ingår i: Quantum Bio-Informatics V: Proceedings of the Quantum Bio-Informatics 2011 : <em>Tokyo University of Science, Japan, </em><em>7 – 12 March 2011</em>. - Singapore : World Scientific. - 9789814460019 ; , s. 171-180
  • Konferensbidrag (refereegranskat)abstract
    • We propose a multiple-photon absorption attack on Quantum Key Distribution protocols. In this attack, the eavesdropper (Eve) is in control of the source and sends pulses correlated in polarization (but not entangled) containing several photons at frequencies for which only multiple-photon absorptions are possible in Alice's and Bob's detectors. Whenever the number of photons from one pulse are dispatched in insufficient number to trigger a multiple-photon absorption in either channel, the pulse remains undetected. We show that this simple feature is enough to reproduce the type of statistics on the detected pulses that are considered as indicating a secure quantum key distribution in entangled-based protocols, even though the source is controlled by Eve, and we discuss possible countermeasures.

  • Ergodicity criteria for non-expanding transformations of 2-adic spheres
  • 2014
  • Ingår i: Discrete and Continuous Dynamical Systems. - : American Institute of Mathematical Sciences (AIMS). - 1078-0947 .- 1553-5231. ; 34:2, s. 367-377
  • Tidskriftsartikel (refereegranskat)abstract
    • In the paper, we obtain necessary and sufficient conditions for ergodicity (with respect to the normalized Haar measure) of discrete dynamical systems < f; S2-r (a)> on 2-adic spheres S2-r (a) of radius 2(-r), r >= 1, centered at some point a from the ultrametric space of 2-adic integers Z(2). The map f: Z(2) -> Z(2) is assumed to be non-expanding and measure-preserving; that is, f satisfies a Lipschitz condition with a constant 1 with respect to the 2-adic metric, and f preserves a natural probability measure on Z(2), the Haar measure mu(2) on Z(2) which is normalized so that mu(2)(Z(2)) = 1.

  • T-functions revisited : new criteria for bijectivity/transitivity
  • 2014
  • Ingår i: Designs, Codes and Cryptography. - : Springer Netherlands. - 0925-1022 .- 1573-7586. ; 71:3, s. 383-407
  • Tidskriftsartikel (refereegranskat)abstract
    • The paper presents new criteria for bijectivity/transitivity of T-functions and a fast knapsack-like algorithm of evaluation of a T-function. Our approach is based on non-Archimedean ergodic theory: Both the criteria and algorithm use van der Put series to represent 1-Lipschitz p-adic functions and to study measure-preservation/ergodicity of these.
