“…To achieve post-quantum security, scholars have conducted many effective works on quantum signatures [23][24][25][26][27][28][29][30][31][32]. In contrast, the adoption of a signature in a relay chain and how to enhance cross-chain transaction security and improve consensus transmission in heterogeneous blockchain is rarely investigated.…”

As a typical cross-chain technology, the relay chain is widely applied. The transaction security in the cross-chain application of a traditional relay chain depends on the reliability of the relay part, which relies on the autonomous performance of the relay chain. However, this will lead to the risk of trust breach. There are three main security concerns: 1) No security access control for authentication; 2) Consensus transmission depends on the authority of the relay node; 3) Potential security threats from quantum computing attacks. To tackle these issues, a quantum cross-chain model (QCC) is proposed to provide post-quantum security. The QCC offers an access control policy for the global identity of application chains and two-way authentication for the cross-chain network, and a secure solution that deploys a quantum ring signature scheme (QRS) provided with audit and key-loss security for cross-chain transactions, contributing to decentralization, reliability, consensus transmissionand security of the relay chain. From a system security perspective, the security of QCC is enhanced by the underlying cryptographic algorithm--QRS, eliminating under-layer attacks and bringing a stronger guarantee for the security and scalability of upper-layer applications. In addition, the model has the advantage of scalability and supports multi-party transactions.

“…In the SQKD protocol, classical participant was limited to perform some specific operations, such as sending and preparing qubits in Z-basis, measuring and reordering qubits, and directly reflecting qubits [7]. Since then, numerous semiquantum protocols have been proposed, such as semi-quantum private comparison [8][9][10], semi-quantum identification [11], semi-quantum signature [12,13], semi-quantum secret sharing [14,15], and SQKD [16][17][18][19].…”

A novel measurement-free mediated semi-quantum key distribution (MSQKD) protocol is proposed based on single-particle states. It enables two classical users to establish a secret key with the assistance of a third party. This protocol simplifies the third party’s role to solely generating qubits in X-basis and conducting Bell measurements. A distinctive feature of this protocol is the efficient grouping and reordering of qubits by the classical users with a minimum of three delay lines. Security analyses demonstrate that the protocol can withstand various attack strategies, including collective attack, measurement attack, fake state attack, and modification attack. The noise tolerance is given by deriving a lower bound of the protocol’s key rate in the asymptotic scenario. Simulations on the IBM Quantum Experience platform are conducted to illustrate the feasibility of this protocol. Compared with existing MSQKD protocols, the proposed protocol consumes fewer quantum resources and achieves a qubit efficiency of 1/8.

This study tackles critical issues in semi‐quantum signature (SQS) protocols to enhance security and efficiency. It revisits Xia et al.’s SQS protocol, which uses EPR steering for security but introduces inconsistencies in a semi‐quantum environment. Xia et al. assume that both the signatory and arbitrator have full quantum capabilities, while the verifier only has partial capabilities, making them a classical participant. However, their protocol requires the verifier to perform eavesdropping checks, necessitating quantum storage, which is not aligned with a semi‐quantum environment. The study proposes a novel SQS protocol using EPR steering and single photons, with pre‐shared keys to determine photon arrangements to address this. This ensures that only the communicating parties know the inspection and message transmission locations, solving the quantum storage issue and enabling efficient eavesdropper detection and identity authentication. This new protocol adheres to semi‐quantum principles and sets a foundation for future advancements in quantum cryptography and secure communication.
