This shift has made the sector highly vulnerable to cyber-attacks, identity theft, and large-scale data breaches. The increasing reliance on classical cryptography, which is threatened by the emergence of quantum computing, presents a pressing security concern. Quantum computers, using algorithms such as Short’s, have the potential to break widely used cryptographic systems like RSA and ECC, thereby compromising financial transactions and personal data security. In this context, Quantum Cryptography, particularly Quantum Key Distribution (QKD), offers a promising alternative. Unlike classical cryptography, QKD leverages the principles of quantum mechanics to provide unconditional security by detecting eavesdropping attempts and ensuring tamper-proof communication channels. This paper explores the application of quantum cryptography in securing financial transactions and sensitive data within the tourism industry. It highlights the limitations of current systems, examines QKD’s potential applications in tourism networks, and proposes a framework for its adoption in booking systems, payment gateways, and traveller identity management. The study also addresses infrastructure challenges, scalability issues, and future prospects of integrating quantum cryptography into global tourism systems. Introduction Tourism is one of the largest global industries, contributing significantly to GDP, employment, and cross-border trade. With increasing digitalization, modern tourism relies heavily on online booking platforms, mobile applications, digital wallets, and biometric verification systems. These systems handle massive volumes of sensitive information, such as passport details, credit card numbers, health records, and travel histories. Cyber security therefore becomes a critical component of maintaining trust in tourism services. However, the rise of advanced hacking techniques and the looming threat of quantum computing have made classical encryption methods less reliable. RSA and ECC, which form the backbone of current secure communication, are at risk of becoming obsolete as quantum computers mature. Short’s algorithm can efficiently factor large numbers and solve discrete logarithm problems in polynomial time, threatening the security foundations of these algorithms [2]. Tourism, being a highly globalized and interconnected industry, is particularly vulnerable. A cyber-attack on an airline reservation system, hotel chain, or online travel agency can expose millions of customer records at once. For example, the 2018 Marriott data breach. compromised over 500 million customer records, including passport numbers and credit card information [4]. Such incidents not only cause financial losses but also erode Traveller trust. Quantum cryptography, based on the laws of quantum mechanics, provides a potential solution. Its most well-known application, Quantum Key Distribution (QKD), allows two parties to share a secure encryption key in such a way that any eavesdropping attempt can be detected. Unlike classical cryptography, which depends on computational difficulty, quantum cryptography offers information-theoretic security This makes it an attractive candidate for securing tourism transactions in the era of quantum computing.

ISSN : 2230-9578 | Website: https://jrdrvb.org Volume-17, Issue-10(V)| October2025 68 This paper aims to analyse how quantum cryptography can transform cyber security in the tourism industry, propose a framework for its implementation, and assess both challenges and future opportunities. Literature Review Tourism and Cyber security The tourism industry has increasingly become a target for cybercriminals. Studies reveal that airlines, hotel chains, and booking platforms frequently suffer from phishing, ransomware, and identity theft [4]. High-value targets include reservation databases, payment systems, and loyalty program accounts. With the adoption of smart tourism technologies and IoT-enabled devices in airports and hotels, attack surfaces are expanding further. Quantum Computing Threats Quantum computing presents a disruptive challenge to classical cryptography. Short’s algorithm [2] demonstrates that quantum computers can efficiently break RSA and ECC, which secure most online financial transactions today. The timeline for practical quantum computers is uncertain, but global institutions like the U.S. National Institute of Standards and Technology (NIST) have already begun the process of standardizing quantumresistant cryptographic algorithms. Quantum Key Distribution (QKD) Bennett and Brassard’s BB84 protocol (1984) [1] marked the beginning of quantum cryptography research. Subsequent protocols, such as E91 and continuous-variable QKD, have expanded possibilities for secure communications. QKD uses photons as carriers of quantum information, ensuring that any interception alters the state of the system and reveals the intrusion. Experimental trials have successfully demonstrated QKD across fiber optic cables and satellite links, with real-world deployments in finance and government communication networks [3]. Industry Use Cases Quantum-secure networks are already being tested in defence, banking, and critical infrastructure. For example, China has launched the Micius satellite for satellite-based QKD, while European initiatives such as the European Quantum Communication Infrastructure (EuroQCI) aim to build continental-scale secure networks [5]. Given the globalized and cross-border nature of tourism, the industry is a natural candidate for similar adoption. Objectives 1. To analyse cyber security challenges in the tourism industry. 2.

Scenario Analysis: Projection of how QKD could integrate with emerging technologies like AI and block chain in tourism. Proposed Framework for Quantum-Secure Tourism Transactions QKD for Online Bookings Tourism platforms such as Expedia, Booking.com, and airline reservation systems can integrate QKD to secure booking transactions. Secure photon-based keys would protect customer identity, passport numbers, and payment information. Block chain + Quantum Cryptography Block chain technology provides decentralization and transparency, while QKD ensures the security of private keys. Together, they can enable tamper-proof tourism records, loyalty programs, and smart contracts for travel insurance. Quantum-Safe Payment Gateways Digital wallets like PayPal, Google Pay, and Alipay can adopt quantum-secure protocols to protect credit card transactions from interception. Financial institutions can deploy QKD-secured networks between payment processors and banks. Traveller Identity Protection Biometric authentication and e-passports are increasingly used in airports. QKD-secured communication between border control systems and central databases can prevent identity theft. Additionally, quantum-secure mobile applications could provide Travellers with encrypted digital identities. Journal of Research and Development Peer Reviewed International, Open Access Journal.
