The widespread use of mobile electronic devices increases the complexities of mobile security. This paper aims to provide a secure communication environment for smartphone users. Some research proves that the one-time pad is one of the securest encryption methods, and the key distribution problem can be solved by using the QKD (quantum key distribution). The objective of this project is to design an Android APP (application) to exchange several random keys between mobile phones. Inspired by QKD, the developed APP uses the quick response (QR) code as a carrier to dispatch large amounts of one-time keys. After evaluating the performance of APP, it allows the mobile phone to capture and decode 1800 bytes of random data in 600ms. The continuous scanning mode of APP is designed to improve the overall transmission performance and user experience, and the maximum transmission rate of this mode is around 2200 bytes/s. The omnidirectional readability and error correction capability of QR code gives it better real-life application, and the features of adequate storage capacity and quick response optimize overall transmission efficiency. The security of this APP is guaranteed since QR code is exchanged face-to-face, eliminating the risk of being eavesdropped. Also, the id of QR code is the only message that would be transmitted through the whole communication. The experimental results show this project can achieve superior transmission performance, and the correlation between the transmission rate of the system and several parameters, such as the QR code size, has been analyzed. In addition, some existing technologies and the main findings in the context of the project are summarized and critically compared in detail.
In order to satisfy the demand of mobile secure communication for quantum keys, this study proposes a commercial quantum key distribution (QKD) based quantum key injection scheme for mobile terminals. It integrates a quantum network with a classic network, employs a quantum key injection device, and applies an encryption strategy to securely transmit the quantum key from the quantum network to the classic network for injection into a mobile terminal.Experimental results in a real quantum key distribution environment show that the fusion network runs stably, and the injection of the quantum key at the mobile terminal is realised effectively, which can meet the demands of mobile secure communication for quantum keys.
Abstract In order to handle the safety problems in mobile communication systems, a mobile identity authentication scheme based on QKD and IBE is proposed. First, the quantum key distribution technology is introduced to handle the safety problems between the private key generator and the cloud services. Next, the IBE algorithm is introduced to encrypt IMSI which makes the scheme more flexible and more efficient. Finally, the quantum time parameter is proposed to manage users’ secret key. Comparing with the existing schemes, the proposed scheme can make full use of the advantages of the QKD and IBE. The mobile identity authentication scheme based on QKD and IBE can be more safe and more efficient.
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.
Quantum computing is a potentially significant threat to classical cryptographic methods, commonly influenced for mobile communication security. In this paper, we propose one secure channel for private, personal mobile devices that are based not only on post-quantum cryptographically algorithm but also to secure communications in the quantum era. NIST-spec kemsKyber2 and Saber represent for irreplaceable session keys in communication against prospective quantum threats. The keys are periodically replaced in order to provide forward secrecy and to protect against an eventual compromise. In addition to the features of mobile platforms, the scheme employs a lightweight authentication protocol applied to lattice-based cryptography which has been shown to be secure and low resource overhead. Testing the proposed solution was practicable and wielded manageable results since it was performed on Android devices with an average key exchange latency of less than 250 milliseconds and a secure message delivery of below 500 milliseconds without compromising the AES-256 equivalence level of privacy. The engineers and software developers with the results from this study could safely claim that practically, it is indeed doable to transfer secure messages on mobile platforms in the post-quantum era and they’d have that same level of confidence with respect to the adoption of cipher suites based on post-quantum standards within any future communication systems.Keywords: Post-quantum cryptography, quantum-resistant encryption, key encapsulation mechanism (KEM), end-to-end encryption (E2EE), quantum key distribution (QKD), mobile communication security, lattice-based cryptography, publickey infrastructure (PKI), quantum computing threats.
Abstract A practical E-payment protocol is presented in this paper. It is based on quantum multi-proxy blind signature. Adopting the techniques of quantum key distribution, one-time pad and quantum multi-proxy blind signature, our E-payment system could protect user’s anonymity as the traditional E-payment systems do, and also have unconditional security, which the classical E-payment systems can not provide. Furthermore, compared with the existing quantum E-payment systems, this practical system could not only support mobile E-payment transactions but also inter-bank transactions .
