Quantum Cryptography: Realizing next generation information security
Payal P. Kilor · 2014
Quantum cryptography is a technology that ensures ultimate security. Compared to current cryptography that could be defeated by by the development of an ultra high-speed computer, quantum cryptography ensures secure communication because it is based on the fundamental physical laws. It is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. Quantum cryptography is a new method for secret communications offering the ultimate security assurance of the inviolability of a Law of Nature. The quantum cryptography relies relies on two important elements of quantum mechanics-the Heisenberg Uncertainty principle and the principle of photon polarization. This research paper concentrates on the principle of quantum cryptography, and how this technology contributes to the network security. This paper outlines the real world application implementation of this technology and the future direction in which quantum cryptography accelerates.
