Tittel, Practical aspects of Quantum cryptographic key distribution
- J. Cryptol
"... Abstract. Performance of various experimental realizations of quantum cryptographic protocols using polarization or phase coding are compared, including a new self-balanced interferometric setup using Faraday mirrors. The importance of detector noise is illustrated and means of reducing it are pres ..."

QUANTUM CRYPTOGRAPHIC PROTOCOLS FOR SECURE COMMUNICATION
, 2009
"... Abstract: Quantum Cryptography offers a secure method of sharing sequences of random numbers to be used as cryptographic keys. It can potentially eliminate many of the weaknesses of classical cryptographic methods. In this paper, we survey some results in quantum cryptography. After a brief introduc ..."

Cryptographic Distinguishability Measures for Quantum-Mechanical States
- IEEE Trans. Inform. Theory 45. No
, 1999
"... This paper, mostly expository in nature, surveys four measures of distinguishability for quantum-mechanical states. This is done from the point of view of the cryptographer with a particular eye on applications in quantum cryptography. Each of the measures considered is rooted in an analogous classi ..."

Quantum Cryptography and Quantum Key Distribution
"... Why Quantum Cryptography? As we have seen during the course, modern cryptography relies on the computational inability of an adversary to break an encryption scheme in polynomial time. While this is in general a strong enough assumption, it is not enough to guarantee the long-term security of an enc ..."

Cryptographic Key Generation based on Contextual Information: A Review
"... With the capabilities of computing increasing by leaps and bounds, the need for trusted communication also rises. The present state of ensuring secure communication between devices largely re-lies on the use of cryptographic keys. The primitive and ad-vanced key generation strategies involve the use ..."

for this purpose. This pa-per presents a detailed survey on the cryptographic techniques for key generation based on contextual information. A brief compar-ison on the current techniques is also presented in this survey.
Purpose
"... This article reviews exposure information available for trichloroethylene (TCE) and assesses the magnitude of human exposure. The primary sources releasing TCE into the environment are metal cleaning and degreasing operations. Releases occur into all media but mostly into the air due to its volatili ..."

using TCE products in areas of poor ventilation. More current and more extensive data on TCE levels in indoor air, water, and soil are needed to better characterize the distribution of background exposures in the general population and elevated exposures in special subpopulations. Key words: exposure
SECURITY USING QUANTUM KEY DISTRIBUTION PROTOCOLS (QKDPs)
"... Abstract — Most cryptographic mechanisms such as symmetric and asymmetric cryptography, often involve the use of cryptographic keys. However, all cryptographic techniques will be ineffective if the key distribution mechanism is weak. Quantum Key Distribution or Quantum Cryptography is attracting muc ..."

, 2003
"... We introduce the use of Fourier analysis on lattices as an integral part of a lattice based construction. The tools we develop provide an elegant description of certain Gaussian distributions around lattice points. Our results include two cryptographic constructions that are based on the worst-case ..."

Some attacks on quantum-based cryptographic protocols
- Quant. Inform. and Comp
, 2005
"... Quantum-based cryptographic protocols are often said to enjoy security guaranteed by the fundamental laws of physics. However, subtle attacks that are outside the original design of the protocols may allow eavesdroppers to break those protocols. As an example, we will give a peeking attack against a ..."
