Nowadays, the information is exchanged among the computer network. These data and information are involved in business, military, academic education, research and etc. which are shared around the world in both private and public network. Since, many categories of data are required restriction on authorization of access, modify, delete and insert, security in communication is increasingly important to the network communication. Currently, computer security applies mathematic theory to computer security for encrypting and decrypting on both sender and receiver. To use security attack with high performance computer (e.g. quantum computer), attacker can find a key and then obtains the data in feasible period. Quantum cryptography is one of the solutions that use property of polarization to ensure that transmitted data is not trapped by eavesdropper. Quantum cryptography is improved significantly in the last decades including the most two dominant protocol BB84 and BB92.
Quantum cryptography represents a revolutionary approach to securing data in the era of quantum computing. Traditional cryptographic methods, which are the backbone of modern digital security, are vulnerable to the computational power of quantum computers. Quantum cryptography, leveraging the principles of quantum mechanics, offers a fundamentally more secure method of encryption that is resistant to the threats posed by quantum-based attacks. This paper explores the fundamental principles of quantum cryptography, the technologies driving its development, and its potential applications in safeguarding sensitive information. We discuss quantum key distribution (QKD) and quantum encryption protocols as the primary tools in this new paradigm, as well as the challenges and limitations of implementing quantum cryptography in real-world systems. The paper concludes by considering the future implications of quantum cryptography for global data protection, its integration with classical encryption techniques, and the steps required to transition to a quantum-secure world.
Quantum computing represents a transformative advancement in computational power, with profound implications for cryptographic systems. This paper explores the intersection of quantum computing and cryptography, examining the potential for quantum computers to both break traditional cryptographic algorithms and enable new forms of secure communication. Classical cryptographic systems, such as RSA and ECC, rely on the computational difficulty of problems like integer factorization and discrete logarithms. However, quantum algorithms, notably Shor's algorithm, can solve these problems exponentially faster than the best-known classical algorithms, posing a significant threat to the security of current cryptographic practices. This vulnerability necessitates the development and implementation of quantum-resistant algorithms to ensure data security in a post-quantum world. The paper reviews the state-of-the-art in quantum-resistant cryptographic algorithms, including lattice-based, hash-based, code-based, and multivariate polynomial cryptography. These algorithms are analyzed for their security properties, efficiency, and practicality for real-world deployment. Additionally, the paper discusses the ongoing standardization efforts led by organizations such as NIST, which are crucial for establishing widely accepted quantum-safe cryptographic protocols. Beyond the threat posed by quantum computing, this paper also highlights the potential benefits quantum computing can bring to cryptographic systems. Quantum Key Distribution (QKD) is one such advancement, offering theoretically unbreakable encryption by leveraging the principles of quantum mechanics. QKD enables secure communication channels that are immune to any computational advances, including those of quantum computers, by ensuring that any attempt at eavesdropping can be detected. The practical implementation challenges of QKD and other quantum cryptographic protocols are also addressed, including issues related to transmission distance, error rates, and integration with existing communication infrastructures. Experimental results from recent QKD trials are presented, showcasing significant progress in extending the viability of quantum-secure communication over long distances. Furthermore, the paper delves into the hybrid approaches combining classical and quantum cryptographic techniques. These approaches aim to leverage the strengths of both paradigms to enhance security and performance. For instance, hybrid protocols might use classical encryption for bulk data transfer, supplemented by quantum techniques for key exchange, thereby ensuring robust security even against future quantum adversaries. In conclusion, while quantum computing poses substantial risks to existing cryptographic systems, it also offers novel opportunities for creating highly secure communication protocols. The transition to quantum-safe cryptography is imperative to protect sensitive information in the quantum era. This paper underscores the urgency of advancing quantum-resistant cryptographic research, promoting international collaboration for standardization, and exploring innovative applications of quantum technologies in cryptography. Continued research and development in these areas are essential to stay ahead of the evolving threat landscape and harness the full potential of quantum computing for secure communications.

Cryptography is an art and science of secure communication. Here the sender and receiver are guaranteed the security through encryption of their data, with the help of a common key. Both the parties should agree on this key prior to communication. The cryptographic systems which perform these tasks are designed to keep the key secret while assuming that the algorithm used for encryption and decryption is public. Thus key exchange is a very sensitive issue. In modern cryptographic algorithms this security is based on the mathematical complexity of the algorithm. But quantum computation is expected to revolutionize computing paradigm in near future. This presents a challenge amongst the researchers to develop new cryptographic techniques that can survive the quantum computing era. This paper reviews the radical use of quantum mechanics for cryptography.
