Abstract

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 .

An E-payment System Based on Quantum Blind and Group Signature

Xiaojun Wen, Zhe Nie

In this paper, a new E-payment system based on quantum blind and group signature is proposed. Existing E-payment systems based on classical cryptography cannot guarantee the security with the emergency of quantum computers. Compared to the existing E-payment system, our quantum E-payment scheme could protect not only the user's anonymity but also the inner structure of customer group. In addition, our system adopts quantum key distribution, one-time pad, and audit mechanism to ensure unconditional security.

An E-payment system based on quantum group signature

Xiaojun Wen

Security and anonymity are essential to E-payment systems. However, existing E-payment systems will easily be broken into soon with the emergence of quantum computers. In this paper, we propose an E-payment system based on quantum group signature. In contrast to classical E-payment systems, our quantum E-payment system can protect not only the users' anonymity but also the inner structure of customer groups. Because of adopting the two techniques of quantum key distribution, a one-time pad and quantum group signature, unconditional security of our E-payment system is guaranteed.

A quantum blind signature scheme for electronic payments

Siavash Khodambashi, Ali Zakerolhosseini

On-line merchants must have security protocol and procedures in place to carry out transactions more securely, Due to the popularity of e-commerce payment systems and the widespread use of the internet-based shopping and banking. In this paper we introduce an original blind signature based on quantum cryptographic principles providing unconditional security for off-line transactions. The proposed scheme guarantees the security of payment in real applications by the laws of quantum mechanics. We describe our proposed scheme in detail through a real example and discuss about its unconditional security.

An anonymous electronic payment scheme based on controlled quantum teleportation

Mengdie Li, Daicao Wan, Meng Jing +2 more

With the in-depth development of the digital economy and the escalating demands for transaction security and quantum attack resistance in electronic payment scenarios, quantum signature is gradually emerging as a core research direction in the construction of electronic payment security systems. Addressing the requirements for anonymity and security in electronic payment scenarios, this paper proposes an electronic payment scheme based on controlled quantum teleportation. During the implementation of the scheme, the quantum entanglement characteristics of the four-particle entangled state, the core logic of controlled quantum teleportation, the privacy protection features of proxy blind signature technology, and the technical advantages of superdense coding are integrated to provide security guarantees for the payment process. Meanwhile, the proposed scheme builds a payment system relying on quantum key distribution protocols, forming a payment system with information-theoretic security attributes. This effectively overcomes the limitation that traditional UnionPay payment systems rely on computational complexity at the security level. In addition, the scheme satisfies nonrepudiation and unforgeability and possesses the capability to resist interception-resending attacks.

A Quantum Multi-agent Blind Signature Scheme

Jingjing Chen, Fucheng You

Abstract With the development of information society, people are increasingly concerned about the security problems caused by information leakage, and digital signatures play an irreplaceable and important role in the protection of information security, which replace traditional manual signatures and seals in the network environment and have important roles such as anti-forgery, anti-tampering, anti-replay, identifiable identity and confidentiality [1]. However, with the in-depth study of quantum mechanics, it has been found that the confidentiality mechanism of classical digital signatures is under serious threat. Since quantum computing is a parallel operation with exponentially increasing operational capability, a series of complex mathematically difficult problems can be rapidly overcome. Based on the above, this paper proposes a multiple agent blind signature scheme, which adopts the key technologies such as the Unitary transformation and Hadamard gate operation, and adds multiple agent signature to quantum signature to improve the efficiency of the protocol, and adds blind signature to improve the security of the protocol. At the same time, the scheme uses quantum key distribution to ensure its unconditional security, which is applicable in systems such as electronic voting and electronic payment, and has certain anti-attack capability [2].
