Abstract

The surging interest in digitalization has revitalized research for digital business model. Mobile Internet of Things (IoT) terminals will reach billions and become an important infrastructure for a digital and intelligent society. In the digital business model of IoT terminals, the electronic seal of commercial contracts are especially investigated to provide the same level security as guaranteed by the traditional seal. However, the existing electronic seal is only applicable to the centralized network applications, which severely relies on the certificate authority. In this paper, we propose a blockchain-based multi-signature smart contract electronic seal scheme. The key of our design is to deploy a smart contract for business parties on Ethereum for secure electronic seal towards mobile IoT terminals. Unlike the traditional seal, this electronic seal is verified and managed collectively by all mining nodes. Combining it with optimizations in terms of a multi-signature algorithm encoded in the smart contract, our design achieves complete digital contract functionality for all business participants of terminals. As an example, we demonstrate an implementation on the Goerli testnet of the Ethereum network with the smart contract deployment. The security analysis and evaluation demonstrate that our design is secure in its multi-signature implementation and can be used in practice.

基于区块链的多签名智能合约电子印章定位移动物联网终端

人们对数字化的兴趣与日俱增，为数字化商业模式的研究注入了新的活力。移动物联网（IoT）终端将达到数十亿台，成为数字化和智能化社会的重要基础设施。在物联网终端的数字化商业模式中，商业合同的电子印章是特别需要研究的，以提供与传统印章同等的安全保障。然而，现有的电子印章只适用于集中式网络应用，严重依赖证书颁发机构。本文提出了一种基于区块链的多签名智能合约电子印章方案。我们设计的关键是在以太坊上为业务方部署智能合约，以实现面向移动物联网终端的安全电子印章。与传统印章不同，该电子印章由所有挖矿节点集体验证和管理。结合智能合约中编码的多重签名算法的优化，我们的设计为终端的所有业务参与者实现了完整的数字合约功能。我们以以太坊网络的 Goerli 测试网为例，展示了智能合约部署的实施情况。安全分析和评估表明，我们的设计在多签名实现中是安全的，可以在实践中使用。

期刊介绍： The aim of the Peer-to-Peer Networking and Applications journal is to disseminate state-of-the-art research and development results in this rapidly growing research area, to facilitate the deployment of P2P networking and applications, and to bring together the academic and industry communities, with the goal of fostering interaction to promote further research interests and activities, thus enabling new P2P applications and services. The journal not only addresses research topics related to networking and communications theory, but also considers the standardization, economic, and engineering aspects of P2P technologies, and their impacts on software engineering, computer engineering, networked communication, and security. The journal serves as a forum for tackling the technical problems arising from both file sharing and media streaming applications. It also includes state-of-the-art technologies in the P2P security domain. Peer-to-Peer Networking and Applications publishes regular papers, tutorials and review papers, case studies, and correspondence from the research, development, and standardization communities. Papers addressing system, application, and service issues are encouraged.
