According to market research firm Market Research Media, global quantum cryptography
communications will grow into a 26.
was proposed by Bennett and Brassard (40) in 1984 as a technology to distribute secure keys by using quantum media.
Niemiec, Design, Construction and Verification of a High-Level Security Protocol Allowing to Apply the Quantum Cryptography
in Communication Networks.
Theoretically, a quantum computer would be able to break current encryption systems, but quantum cryptography
is arguably unbreakable even by a quantum computer.
However, a theoretical physicist Karl Svozil disagrees that the protocol is entirely secure and said that the protocol required the classical channel to be uncompromised for quantum cryptography
to work adding that the newly proposed protocol is 'breakable' by middlemen attacks.
London: Researchers have come up with a way of protecting telecoms networks using quantum cryptography
without the need for expensive dedicated optical fibre links.
The requirement of separate fibres has greatly restricted the applications of quantum cryptography
in the past, as unused fibres are not always available for sending the single photons, and even when they are, can be prohibitively expensive," said Andrew Shields from Toshiba Research in Cambridge.
With quantum cryptography
, a quantum cryptographic key is transmitted one photon at a time, the smallest increment possible.
The world's first commercial quantum cryptography
solution was QPN Security Gateway (QPN-8505) proposed by MagiQ Technologies (USA) (QPN .
Born theoretically just a quarter century ago, quantum cryptography
forms the foundation of a burgeoning research enterprise known as quantum information theory, which involves not just quantum communication but also the ambitious goal of quantum computation.
First, they are part of a multi-team effort with NIST to build a compact robust entangled photon source for use in quantum cryptography
This paper explains how cryptography will be benefited from quantum mechanics, through a short introduction to classical cryptography, and the general principles of quantum cryptography
and the BB84 protocol for key distribution.
