“…In the application, Even and Goldreich proposed an on-line/off-line signature scheme (Even et al 1996), which uses the efficient OTS scheme for the on-line signing, along with an ordinary signature scheme used for the off-line phase. Other applications such as TESLA (Perrig et al 2002), wireless security, etc., are also well researched (Perrig et al 2001;Bergadano et al 2002;Buldas et al 2017Buldas et al , 2018.…”

The current development toward quantum attack has shocked our confidence on classical digital signature schemes. As one of the mainstreams of post quantum cryptography primitives, hash-based signature has attracted more and more concern in both cryptographic research and application in recent years. The goal of this paper is to present, classify and discuss different solutions for hash-based signature. Firstly, this paper discusses the research progress in the component of hash-based signature, i.e., one-time signature and few-time signature; then classifies the tree-based public key authentication schemes of hash-based signature into limited number and stateful schemes, unlimited number and stateful schemes and unlimited number and stateless schemes. The above discussion aims to analyze the overall design idea of different categories of hash-based signatures, as well as the construction, security reduction and performance efficiency of specific schemes. Finally, the perspectives and possible development directions of hash-based signature are briefly discussed.

“…Subsequent minor transactions are connected to Tx p,0 via the hash function. Throughout the transaction, the security of each minor transaction hinges on the challenge of calculating the hash inverse function [14]. The concept of the hash chain is illustrated in Figure 1.…”

A Blockchain-Based Continuous Micropayment Scheme Using Lockable Signature

A blockchain-oriented continuous micropayment system forms an integral element of the digital economy, enabling seamless transactions and encouraging minor purchases. However, due to the inherent throughput constraints of blockchain, payment channels (PCs) are customarily deployed for managing high-volume transactions in an off-chain mode. Despite this, the integration of a PC necessitates a trusted intermediary to safeguard transactional security, thereby imposing an extra security assumption as only the initial and concluding transactions are visible to other system participants. To circumvent this limitation, we introduce an innovative micropayment structure utilizing lockable signatures. Each transaction within the PC coalesces into a continuous microtransaction hash-chain (CMHC), precluding unscrupulous users from accessing transactional data during the process. Additionally, all locks within the CMHC remain concealed throughout the transaction, with all information relayed in a tamper-proof manner. We provide a comprehensive security analysis and perform a gamut of evaluations. Empirical evidence indicates that our proposed system outperforms existing state-of-the-art solutions in transaction time and verification expenses. This lockable signature-dependent micropayment system not only ensures robust security but also enhances transactional speed and efficiency, thereby catalyzing the growth of the digital economy.

“…In 2018, Buldas et al presented a hash-based server-supported digital signature scheme. They suggested that the concept of blockchain authenticated data structures, and they presented a blockchain design that could have independent values [34]. The fresh signatures' keys are generated by supporting the server using a hash tree and a hash chain.…”

“…However, according to the protocols discussed in Section 2.2, in most blockchain-based protocols, some entities handle systems. To name a few examples, we can mention those called Server (see [34], Page 5), Verifier (see [17], Page 6), IDM (see [18], Page 2), and Authority (see [37], Page 4). Therefore, it is required that, in addition to the blockchain as the distributed database, there needs to be an entity for initialing the QS-RP, verifying the received proofs, and assigning and sending the whistleblower's reward.…”

The reporting systems are needed to design so that the whistleblower's privacy, report confidentiality, and report integrity should be under-consideration. Additionally, it is expected that the approved report will be accessible publicly and not changed. We believe that blockchain technology is the best choice for reporting systems' infrastructure since it provides a transparent and immutable database. This paper presents the first blockchain-based quantum-secure reporting protocol (QS-RP) using multivariate public key cryptography (MPKC). In the QS-RP, a fast verification mechanism is applied, which makes use of the Merkle technique. The QS-RP provides confidentiality to the selectively secure multi-key (C-SSMK) and unforgeability to selectively secure multi-key (UF-SSMK). Additionally, the QS-RP provides several new features such as report confidentiality before report generation, user/whistleblower privacy, and report integrity. The most important feature of the QS-RP is providing the whistleblower's privacy and report confidentiality against quantum computers. Analysis of the security of the QS-RP indicated the mentioned claims in the random oracle model (ROM). Finally, the QS-RP is compared with other blockchain-based reporting protocols. The comparison shows the QS-RP provides more security features than other reporting protocols, and the performance analysis's results show that it is 90% faster in the execution time on the user side, and it is 66% efficient in the communication overhead in compared to other blockchain-based reporting protocols. Moreover, the QS-RP has no on-chain overhead for whistleblowers.
