Present cryptography algorithms are based on mathematical problem such as factoring two large prime numbers and N vs NP problem. But computing power and evolution in mathematics increases day by day so it’s easy to reverse one way function to quickly such as that of factoring large integers. So the solution is to build a cryptosystem which secure our communication even the computing power is to high so we introduce quantum physics in cryptography which lead to evaluation of quantum cryptography. Quantum cryptography one of the emerging topics in field of computer industry. This paper is an attempt to review fundamentals of quantum cryptography and also analyses few application areas of quantum cryptography and it’s limitation.
Quantum Cryptography: The Future of Internet and Security Management
JMSS, A2Z Journals, 2021
In today's world, the cryptography techniques are used and implemented on the elementary method of finding the prime factor of large integer, which is said to be "Inevitable to Track". But living in an era where nothing is impossible to achieve, so cryptography techniques are exposed to both technologies' advancement in computational power of machines and advancement in the fields of mathematics to break the notion that factoring of large integers into their prime is impossible. To cope up with the threat that cryptography will face is handled by fusion of physics into cryptography, leading to the evolution of Quantum Cryptography. It is one of the fast-growing fields in computer technology. In this paper, I am going to brief the concepts of Quantum Cryptography and how this technology has led to the development of the strategy of complete secure key distribution. The paper covers the loophole present in the modern cryptography techniques, the fundamental principle of quantum cryptography, its implementation in the real world along with the limitation faced in this field, and the possible future of quantum cryptography.
Quantum Cryptography: A Survey
Advances in Intelligent Systems and Computing, 2019
This paper represents the overview of Quantum Cryptography. Cryptography is the art of secrecy and it is the use of quantum mechanical properties to perform cryptographic tasks. It is a way of securing the channel using quantum mechanics properties. There are so many examples of quantum cryptography but the most important example is Quantum Key Distribution, which provides a solution to the breaking of various popular public key encryption and signature schemes (e.g. RSA and ElGamal). This helps to solve the security problems and also makes the communication channel is more secure. There are so many advantages of quantum cryptography, one thing is that the quantum computer gives the quadratic speed up on the general problems and second thing is that the quantum cryptography lies in the fact it allows the completion of various cryptographic tasks. That is proven to be impossible using classical communication.
A Comprehensive Survey on : Quantum Cryptography
2015
Quantum cryptography uses quantum mechanics to guarantee secure communication. It enables two parties to produce a shared random bit string known only to them, which can be used as a key to encrypt and decrypt messages. An important and unique property of quantum cryptography is the ability of the two communicating users to detect the presence of any third party trying to gain knowledge of the key. The security of quantum cryptography relies on the foundations of quantum mechanics, in contrast to traditional public key cryptography which relies on the computational difficulty of certain mathematical functions, and cannot provide any indication of eavesdropping or guarantee of key security. In this paper we are discussing about various protocol introduced, possible attacks on them and prevention of those attacks.

Internet has become a global means of communication, turned our reality upside down. It has transformed communications, to the level that it is now our chosen standard of communication. Although there are many ways to protect information from undesired access, Quantum cryptography can be used to unconditionally secure data communications by applying the laws of quantum physics which overcomes the drawbacks of traditional classical cryptography, which depends on mathematical methods to limit attacks such as eavesdroppers. Quantum cryptography is considered to be a future replica of classical cryptography. In this survey paper, we will discuss about various protocols of cryptography. Also discussing about their vulnerabilities

Quantum computing can be regarded as a disruptive enabling technology that can pose a threat to traditional cryptography as it invented new approaches to encrypt data. This paper will compare the level of security that accompanies quantum algorithms as well as the level of efficiency. Specifically, we examine the impact of efficient quantum computing on traditional cryptography and propose techniques against quantum invasions. Four quantum algorithms are analyzed for their efficiency and security benefits in the post-quantum era: Grover’s Algorithm, Shor’s Algorithm, The Quantum Key Distribution (QKD), Lattice-based cryptography. The results reveal that Grover’s algorithm improves search time complexity from O(n) to O(√n), which is advantageous over large data sets. As it will be clear shortly, Shor’s algorithm challenges RSA encryption because it outperforms classical algorithms in factoring large integers. QKD presents secure key exchange protocols that cannot be breached notwithstanding the attempts made using quantum computing. Lattice-based schemes are quantum-resistant alternatives based on the security of certain hard mathematical problems. Based on our experimental results, computational efficiency can be improved, but new cryptographic systems will have to be developed for the mitigation of quantum-related vulnerabilities. This research shows the importance of quantum-resistant cryptographic techniques to ensure data security in the emerging quantum computing era.
