“…Thus, fewer classical bits are used here to authenticate content that requires a large number of classical bits for storage. Equation (27) gives the quantum bit efficiency of the protocol when n = 2, namely k ide ∈ {0, 1}. As n is increased, the number of useful classical bits N(n) also is increased and min N(n) = n. In summary, the quantum bit efficiency can be expressed as follows:…”

In this work, we propose a bit-oriented QIA protocol based on special properties of quantum rotation and the public key cryptographic framework. The proposed protocol exhibited good resistance to both forward search and measure-resend attacks, whereby its security performance was directly related to the length of the authentication code. From our analysis, it was demonstrated that the protocol has good performance, in terms of quantum bit efficiency. In addition, the protocol is well-expandable. The developed protocol is resource-efficient and can be also applied in quantum computing networks.

“…As a minor protocol, QIA should be used as little as possible to ensure that it does not burden the major protocol in quantum communication networks. Some other protocols [27][28][29] face a similar problem of using too many resources for additional purposes, which seem to deviate from the original intent of QIA.…”

“…However, in Ref. [107], a scheme for blind quantum signaturea task closely related to QIA has been proposed using BQC. This may be mapped to a scheme of QIA and generalizing the idea, efforts may be made to explore the possibility of designing schemes for QIA using the existing and new schemes for BQC.…”

Secure communication has achieved a new dimension with the advent of the schemes of quantum key distribution (QKD) as in contrast to classical cryptography, quantum cryptography can provide unconditional security. However, a successful implementation of a scheme of QKD requires identity authentication as a prerequisite. A security loophole in the identity authentication scheme may lead to the vulnerability of the entire secure communication scheme. Consequently, identity authentication is extremely important and in the last three decades several schemes for identity authentication, using quantum resources have been proposed. The chronological development of these protocols, which are now referred to as quantum identity authentication (QIA) protocols, are briefly reviewed here with specific attention to the causal connection involved in their development. The existing protocols are classified on the basis of the required quantum resources and their relative merits and demerits are analyzed. Further, in the process of the classification of the protocols for QIA, it's observed that the existing protocols can also be classified in a few groups based on the [inherent computational tasks used to design the protocols. Realization of these symmetries has led to the possibility of designing a set of new protocols for quantum identity authentication, which are based on the existing schemes of the secure computational and communication tasks. The security of such protocols is also critically analyzed.

“…One of the most promising applications of quantum computing for e-commerce is in the eld of optimization. E-commerce companies often need to solve complex optimization problems, such as nding the most e cient route for product delivery or determining the optimal pricing strategy [7]. Quantum computers are uniquely suited to solving these problems, as they can consider many possible solutions simultaneously and nd the optimal solution in a fraction of the time it would take a classical computer [9].…”

Currently, E-commerce is widely adopted as it is important for business management and economic growth in the new global economy, and to reach the rapid increasing population. To better manage the e-commerce, it is important to collect and evaluate the Consumer Behaviour data for decision making and optimization. The conventional computing technologies need high amount of power and time for large data analysis. Quantum computing has the potential to analyze the large amount of data more efficiently than classical computing. This paper aims to explore the core process areas that need to be consider by the practitioners for adopting quantum computing in social business. To address the objective of this study, we conducted a literature review and empirical study to explore the core process areas that need to be considered for the consideration of quantum computing in social business. The results show that limited scalability, regulatory challenges, high initial cost, limited availability of quantum resources, education and training and security are the most important process areas that need to be focused by the industry practitioners. The result of this study gives a knowledge base for research and practitioners community to develop the tools and strategies for the adoption of quantum computing in social business.
