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.
In today’s world, security in data communication has become a top-most priority in every organization. In general, cryptography is defined as the methodology to ensure data is secure by employing suitable encryption and decryption techniques. On the transmitter side, the original message is encrypted using a key. Then the encrypted data is decrypted with the duplicate key at the receiver side as per the accepted protocol between the two parties. In conventional cryptographic techniques, eavesdropping is prevented from accessing the contents of encrypted message by employing certain mathematical function and techniques, but this security methodology does not guarantee any key security. In many scenarios, a secure communication link is established by using a key, but a third party with a bad intent may steal the session keys, giving rise to data security, getting compromised. So in this regard, quantum cryptography is a better alternative when it comes to data security integrity. In this research, a detail about quantum cryptography is elaborated on, and also discussed are various concepts like single photon protocol, loss of data in quantum computing, how quantum is affecting computer communication systems. In conventional cryptographic methodology of data transmission and reception, there is always a probability of eavesdropping leading to the compromising of data integrity and security. The solution to this problem can be obtained by integrating the quantum cryptographic technique with data at the sender as well as the receiver, to detect and minimize various errors by employing suitable bit error scheme. This involves the usage of programming language specific to quantum computing like qcl and quipper to achieve efficient encryption and decryption with faster processing capability.
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.
There is growing concern around ensuring security, privacy and integrity of the data and information during communication due to increasing cyber threats. The traditional cryptography techniques could address the security concerns to some extent, but it is not completely free from the cyber-attacks. The new age technology of quantum cryptography has been introduced as one point solution for addressing the security concerns in online communication. This paper discusses the various challenges in traditional cryptography which have been addressed by quantum cryptography. The paper also discusses the various benefits of quantum cryptography and a few concerns related to cost, complexity, range, and implementation. The study considers the future direction in which the quantum cryptography is progressing and deliberates over the related technological advancements.
The security of our data is the prime priority as it is said “Data is the new Oil”. Nowadays, most of our communications are either recorded or forged. There are algorithms used under classical encryption, such as Rivest-Shamir-Adleman (RSA), digital signature, elliptic-curve cryptography (ECC), and more, to protect our communication and data. However, these algorithms are breakable with the help of Quantum Cryptography. In addition, this technology provides the most secure form of communication between entities under the fundamental law of Physics. Here, we are abiding to discuss the term “Quantum Cryptography.” The aim of this paper is to explore the knowledge related to the Quantum Cryptography, Quantum Key Distribution; and their elements, implementation, and the latest research. Moreover, exploration of the loopholes and the security of Internet of Things (IoT) infrastructure and current used classical cryptographic algorithms are described in the paper.
Quantum cryptography promises secure communication protocols that surpass the limitations of classical cryptography. By leveraging the principles of quantum mechanics, particularly the phenomenon of quantum entanglement and the uncertainty principle, quantum cryptography protocols offer provable security guarantees against eavesdropping attacks. In this paper, we provide an overview of quantum cryptography, discussing its theoretical foundations, key protocols such as quantum key distribution (QKD), and experimental implementations. We highlight the advantages of quantum cryptography over classical cryptographic techniques and explore its potential applications in secure communication networks, financial transactions, and data privacy. Furthermore, we discuss ongoing research efforts and challenges in the practical deployment of quantum cryptography systems, including the development of robust quantum hardware and the integration of quantum cryptographic protocols into existing communication infrastructures. Overall, quantum cryptography holds great promise for enabling secure communication channels that are resilient to quantum attacks, paving the way for a new era of ultra-secure information exchange.
