Quantum computation has important impacts on information security and modern cryptography. In 1994, Shor demonstrated that the problem of finding the prim factors of an integer, and the so called "discrete logarithm problem" could be solved efficiently on a quantum computer. Quantum information can also be proved to devise unconditionally secure cryptography protocols. In this paper, we introduce the most recent research progress in quantum information security and quantum coding theory and review several quantum quantum cryptography protocols that we have proposed.

In the era of information technology the need for secure communication has become increasingly important. Cryptography is a technology for creating the core of information security we use cryptography for making data secure which is the science of information protection from unauthorized interception and tempering. Most modern cryptographic studies design cryptosystems and algorithms using mathematical concepts which are based either on factorization or on discrete logarithm problem. In recent years quantum information research has lead to the discovery of a number of remarkable new paradigms for information processing and communication. These developments include quantum cryptography schemes that offer unconditionally secure information transport guaranteed by quantum-mechanical laws, which provide protection of system security, and optimization of system efficiency and detects intrusion and wiretap. Today quantum cryptography is used in various application for transferring secure data without the fear of keys being compromised. This paper reviews the various areas where quantum cryptography is successfully implemented, its advantages disadvantages & technical issues.
Quantum computing introduces a new paradigm that brings about, by its very nature, revolutionary changes in cryptography and data security. This section will shortly discuss some of the impacts of quantum computing technologies on cryptographic protocols, focusing on the various vulnerabilities introduced by algorithms such as Shor's algorithm, capable of solving some problems-integer factorization and discrete logarithms-provided that polynomial complexity is achieved on quantum computers. Quantum algorithms will soon render traditional cryptographic techniques using RSA and ECC vulnerable, hence the development need for PQC techniques. It purports to analyze the available research and discusses the development, challenges, and future directions of quantum- resistant cryptographic methodologies. This paper emphasizes that transitioning towards PQC is urgent to maintain all attributes of data, such as confidentiality, integrity, and authentication in the quantum computing era. QKD emerges as a promising approach that uses the principles of quantum mechanics to provide physical-layer security for communication channels. Based on these phases, the paper develops into recommendations on building resilience in cryptography with the prospect of quantum computing.
Quantum computing is poised to revolutionize numerous sectors, with cryptographic security identified as one of the most critically affected domains. For instance, Elliptic Curve Cryptography (ECC) and RSA, two traditional encryption techniques, rely on the computational difficulty of integer factorization and discrete logarithms. Nevertheless, quantum algorithms, particularly Shor's algorithm, which jeopardizes the security of existing cryptographic systems, may be able to address these problems successfully. This discovery necessitates the development of cryptographic techniques that are impervious to quantum attacks. The study of post-quantum cryptography (PQC), which includes hash-based, lattice-based, and other quantum-resistant algorithms, is becoming essential to ensuring the long-term confidentiality and integrity of data. This paper explores the basic concepts of quantum computing, their relationship to cryptographic privacy, and potential solutions for the associated security problems in the quantum age.
Quantum computing is a big change in the way computers work, and it promises to be much faster than traditional systems. This new technology brings both huge benefits and huge problems, especially when it comes to cryptographic security measures. Classical encryption algorithms, like RSA and ECC, depend on the fact that some math problems are hard, like discrete logarithms and integer factorization. Quantum algorithms, like Shor's algorithm, can solve these problems quickly. Because of this, the development of scalable quantum computers poses a danger to the basic safety of the cryptography methods that are widely used today. This short summary looks at the big effects that quantum computing will have on the safety of cryptography. It looks at the security holes that quantum algorithms create and stresses how important it is to find answers for post-quantum cryptography (PQC). PQC wants to make programs that can't be broken by quantum attacks. This will make sure that digital interactions can still be private, secure, and real in a world powered by quantum computers. Also, switching to PQC comes with a lot of problems, such as implementing algorithms, making sure they are all the same, and getting people to use them in a lot of different technology environments. The abstract talks about current research projects and foreign partnerships that aim to standardize and implement PQC. It stresses how important it is to plan ahead to reduce the risks of the future.
Abstract: Shor’s algorithms for the integer factorization and the discrete logarithm problems can be regarded as a negative effect of the quantum mechanism on publickey cryptography. From the computational point of view, his algorithms illustrate that quantum computation could be more powerful. It is natural to consider that the power of quantum computation could be exploited to withstand even quantum adversaries. Over the last decade, quantum cryptography has been discussed and developed even from the computational complexity-theoretic point of view. In this paper, we will survey what has been studied in quantum computational cryptography. Key Words: computational cryptography, quantum computing, quantum cryptography Category: E.3, F.1.1
A quantum computer can destroy most, if not all, of the traditional cryptosystems used in practice, namely, all the systems on the basis of the integer factorization problem (e. g. RSA) or the discrete logarithm problem (both traditional and elliptic curve Diffie-Hellman and DSA, and the whole cryptography based on the pairing). Some classic cryptosystems based on computationally difficult problems are very different from the above and more difficult to solve, they are independent of the quantum computation. In this paper, a review of methods of information security based on quantum and post-quantum technologies was carried out. For each of the methods of information security based on quantum technologies are the advantages and disadvantages. Describes the system of post-quantum cryptography based on lattice theory. The results of the survey allow to formalize the direction of future research of post-quantum methods and development of new effective information security systems using quantum technologies.
