Counter factual quantum cryptography
FREE-DOWNLOADTG Noh – Physical review letters, 2009 Quantum cryptography allows one to distribute a secret key between two remote parties using the fundamental principles of quantum mechanics. The well-known established paradigm for the quantum key distribution relies on the actual transmission of signal particle through a
Position based quantum cryptography
Position based quantum cryptography Impossibility and constructions FREE-DOWNLOADH Buhrman, N Chandran, S Fehr, R Gelles… 2010 In this work, we study position-based cryptography in the quantum setting. The aim is to use the geographical position of a party as its only credential. On the negative side, we show that if adversaries are allowed to share an […]

FREE-DOWNLOAD Quantum Information, Computation and Cryptography, 2010 The Greek words “kryptos” = “hidden” and “logos” = “word” are the etymological sources for “cryptology,” the science of secure communication. Within cryptology, one distinguishes cryptography (or “code-making”) and cryptanalysis (or “code- breaking”). The aim of cryptography is to
