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 introduction to classical cryptography, some fundamental quantum key distribution protocols are reviewed. The issue...

This paper introduces the current state of the development of single photon sources that will play a central role in future quantum information systems. By optically pumping a system consisting of a semiconductor single quantum dot confined in a monolithic microcavity, it is possible to produce a single photon pulse stream at the Fourier transform limit with high efficiency and with a high repe...

Quantum cryptography is a topic of considerable interest. A simple and robust experiment theory for senior level undergraduate investigation quantum key distribution are described. In the proposed experiment, principles from BB84 protocol, used in cryptography, emulated using an optical apparatus computational scripts independently.

In this paper, the systematisation and classification of modern quantum technologies of information security against cyber-terrorist attack are carried out. The characteristic of the basic directions of quantum cryptography from the viewpoint of the quantum technologies used is given. A qualitative analysis of the advantages and disadvantages of concrete quantum protocols is made. The current s...

Systems of Multivariate Quadratic Equations (M Q ) are important in cryptography due to the resistance against attacks that will arise with the advent of quantum computing. Resistant algorithms against attacks based on quantum computing are called post-quantum cryptography. Unbalanced OilVinegar (UOV) is a well known post-quantum signature scheme based on M Q . This paper presents a variation o...

Quantum mechanics is the basic principle which is applied in the cryptographic scenario of quantum cryptography. Present paper provides a conceptual framework on the high level security protocol in Quantum cryptography. This is used as a base for data security through quantum computing in modern cryptosystem. In this paper first of all a detailed description of BB84 protocol with noise and with...

Isogeny-based cryptography using supersingular elliptic curves — most prominently, the constructions of De Feo-Jao-Plut — is one of the few practical candidates for post-quantum public key cryptography. Its formidable security claim is earned through the continual exploration of quantum algorithms for ‘isogeny problems’ and the assessment of the threat they pose to supersingular isogeny-based c...

Electronic communication has become one of the main pillars of modern society and their ongoing boom requires the development of new methods and techniques to secure data transmission. This has been the goal since the onset of cryptography in ancient times. Cryptography may be defined as the art of writing (encryption) and deciphering (decryption) messages in code in order to ensure their confi...

In modern cryptography, block encryption is a fundamental cryptographic primitive. However, it is impossible for block encryption to achieve the same security as one-time pad. Quantum mechanics has changed the modern cryptography, and lots of researches have shown that quantum cryptography can outperform the limitation of traditional cryptography. This article focuses on block encryption of qua...
