چکیده
1. Introduction Quantum cryptography is a technology that ensures ultimate security 1). Compared to current cryptography that could be defeated by the development of an ultra high-speed computer, quantum cryptography ensures secure communication because it is based on the fundamental physical laws. Among the various quantum information technologies, the most extensive research is being conducted on quantum cryptography, including the development of experimental equipment, field tests, and discussions on proposals of new theoretical schemes. This paper outlines the domestic and overseas trends in research and development on quantum cryptography and presents our achievements and current efforts toward its practical application. The security analysis of quantum cryptography, which is attracting an increasing amount of attention, is also discussed.

On the design and security of a lattice-based threshold secret sharing scheme
In this paper, we introduce a method of threshold secret sharing scheme (TSSS) in which secret reconstruction is based on Babai's nearest plane algorithm. In order to supply secure public channels for transmitting shares to parties, we need to ensure that there are no quantum threats to these channels. A solution to this problem can be utilization of lattice-based cryptosystems for these channe...
متن کاملThe Next Level of Information Security: Impact of Quantum Cryptography
By the development of ultra high-speed computers, existing modern cryptography could be failed whereas Quantum cryptography guarantees the secure communication whose security based on the legality of quantum mechanics. This research paper concentrates on the strong basics of quantum cryptography and how it guarantees the secure communication over the network. There are two ways to conduct Quant...
متن کاملQuantum Cryptography: a New Approach to Information Security
Quantum cryptography is an emerging technology in which two parties can secure network Communications by applying the phenomena of quantum physics. The security of these transmissions is based on the inviolability of the laws of quantum mechanics. Quantum cryptography was born in the early seventies when Steven wiesner wrote “conjugate coding”. The quantum cryptography relies on two important e...

For the past decade progress in quantum cryptography changed the status of quantum key distribution (QKD) from laboratory to the practical innovation technology. Quantum cryptography is an emerging technology in which two parties can secure network communications by applying the phenomena of quantum physics. Quantum cryptography applies the uncertainty principle and the no-cloning theorem of qu...
متن کاملCryptography - Wikipedia, the free encyclopedia
Cryptography is an interdisciplinary subject, drawing from several fields. Older forms of cryptography were chiefly concerned with patterns in language. More recently, the emphasis has shifted, and cryptography makes extensive use of mathematics, particularly discrete mathematics, including topics from number theory, information theory, computational complexity, statistics and combinatorics. Cr...
