The increasing reliance on electronic payment systems has caused problems in terms of data protection and fraud control. Traditional cryptographic algorithms like RSA and ECC become increasingly vulnerable with advancements in quantum computing technology, and hence the development of quantum-resistant security protocols is an absolute need. Based on fundamental quantum concepts like quantum connection and the no-cloning theorem, quantum cryptography (QC), along with especially quantum key distribution (QKD), provides an encryption method that is potentially infallible. In order to improve secrecy, integrity, and authentication processes, the current study takes into account the integration of QKD into online payment systems. The use of artificial intelligence (AI) in fraud detection is also discussed in the study, with particular reference to real-time the tracking of transactions and anomaly detection. The susceptibility of QKD-based security protocols to both conventional and quantum-facilitated cyberattacks is determined by comparing conventional cryptographic systems with their quantum-secured counterparts. The study determines that quantum-augmented encryption significantly reduces threats in terms of key distribution and interception of information, hence guaranteeing a safe and forward-thinking digital transactional platform.
With online transactions and processing, a large amount of data is generated in today’s internet world, and securing this information is a challenge. It considers security and privacy as the degree of resistance to information and different transaction details from threats and vulnerabilities. The primary concern in online banking is user authentication, information confidentiality, and the channel/media through which the information is shared. Towards this purpose, the paper majorly focuses on the security techniques under classical and quantum cryptography used in online banking to address the issues and different attacks during service utilization. Paper presents a model used to authenticate a client through quantum-safe channel technique in conjunction with one-time pad (OTP) concept to increase security and avoid reply attacks. The idea of introducing quantum cryptography aims to analyze the performance for the operational feasibility of the proposed solution. Combining quantum computing and classical algorithms can boost fraud detection performance and processing speed in financial transactions. Hence, the proposed scheme considers implementing a hybrid technique and QKD for secure online banking in a quantum cryptography environment.
In today’s online environment, a lot of data is created through online transactions and processing, and protecting this data can be difficult. When talking about security and privacy, it takes into account how resistant information and other transaction data is to threats and flaws. Online banking raises three key concerns: user identity, data confidentiality, and the medium or channel over which the information is conveyed. For this reason, the main focus of this study is on the security methods used in online banking that fall within the categories of classical and quantum cryptography in order to combat multiple attacks and problems that may arise when using the service. The study offers a conceptual model for client authentication using the one-time pad (OTP) idea in conjunction with quantum-safe channel technology to boost security and prevent reply attacks. To assess the performance and determine whether the proposed framework operationally feasible, quantum cryptography is being introduced. The performance and speed of financial transaction processing can be increased by combining quantum computing with traditional algorithms for fraud detection. In order to create a safe key exchange with the help of quantum cryptography, the proposed approach takes this into consideration and implements QKD and QRNG.
Quantum computing's development poses a significant threat to the cryptographic security of current blockchain technologies, potentially undermining the integrity of digital transactions. Quantum computers can break the complex mathematical problems that algorithms like RSA and ECC rely on, which could lead to vulnerabilities such as double-spending and fraud. To address these risks, the blockchain community is exploring quantum-resistant protocols that employ post-quantum cryptographic algorithms, which are designed to withstand quantum computing attacks. Quantum-secure blockchain protocols integrate quantum key distribution (QKD) and post-quantum cryptography (PQC) to enhance security. QKD uses quantum mechanics principles to secure communication channels, ensuring that any attempt to intercept the key introduces detectable anomalies. PQC involves algorithms like lattice-based, hash-based, or multivariate polynomial-based algorithms that are believed to be secure against quantum attacks. These protocols aim to maintain the confidentiality, integrity, and security of data transmitted over the blockchain, ensuring the longevity and reliability of blockchain systems in the face of evolving computational advancements. A quantum-secure blockchain scheme (QSB) utilizes a consensus mechanism, QPoA, and IQS. The QPoA is leveraged for block generation while the IQS is deployed in transaction verification1. Furthermore, the integration of quantum computing with blockchain can address current limitations, such as slow transaction speeds and lack of scalability, by optimizing calculations and enabling smarter, more sophisticated smart contracts. The development and implementation of quantum-resistant blockchains are essential for future-proofing digital transactions and maintaining trust in decentralized systems

Furthermore, challenges such as scalability, high implementation costs, and regulatory considerations are discussed. The paper highlights the urgent need for financial institutions to begin adopting quantum-resistant cryptography to safeguard future financial transactions.
The rapid growth of digital communication has increased the need for highly secure email systems capable of protecting sensitive information from evolving cyber threats. Traditional encryption techniques such as RSA and ECC are becoming vulnerable due to advancements in quantum computing, which can potentially break conventional cryptographic algorithms. To address these challenges, this project proposes a Quantum Secure Email Client Application that integrates post-quantum cryptography (PQC) techniques to ensure end-to-end secure communication. The proposed system employs quantum-resistant encryption algorithms such as lattice-based cryptography, hash-based signatures, or code-based encryption to secure email content, attachments, and user authentication processes.
