Through virtualization and resource integration, cloud computing has expanded its service area and offers a better user experience than the traditional platforms, along with its business operation model bringing huge economic and social benefits. However, a large amount of evidence shows that cloud computing is facing with serious security and trust crisis, and building a trust-enabled transaction environment has become its key factor. The traditional cloud trust model usually adopts a centralized architecture, which causes large management overhead, network congestion and even single point of failure. Furthermore, due to a lack of transparency and traceability, trust evaluation results cannot be fully recognized by all participants. Blockchain is a new and promising decentralized framework and distributed computing paradigm. Its unique features in operating rules and traceability of records ensure the integrity, undeniability and security of the transaction data. Therefore, blockchain is very suitable for constructing a distributed and decentralized trust architecture. This paper carries out a comprehensive survey on blockchain-based trust approaches in cloud computing systems. Based on a novel cloud-edge trust management framework and a double-blockchain structure based cloud transaction model, it identifies the open challenges and gives directions for future research in this field.

云计算系统中基于区块链的信任管理:分类、审查和未来方向

通过虚拟化和资源整合,云计算扩大了服务范围,提供了比传统平台更好的用户体验,其商业运营模式带来了巨大的经济和社会效益。然而,大量证据表明,云计算面临着严重的安全和信任危机,构建信任赋能的交易环境成为其关键因素。传统的云信任模型通常采用集中式架构,导致管理开销大、网络拥塞甚至单点故障。此外,由于缺乏透明度和可追溯性,信任评估结果无法得到所有参与者的充分认可。区块链是一种新的、有前途的去中心化框架和分布式计算范式。其独特的操作规则和记录可追溯性确保了交易数据的完整性、不可否认性和安全性。因此,区块链非常适合构建分布式、去中心化的信任架构。本文对云计算系统中基于区块链的信任方法进行了全面调查。基于一种新颖的云边缘信任管理框架和基于双区块链结构的云交易模型,它识别了该领域的开放挑战并为该领域的未来研究指明了方向。本文对云计算系统中基于区块链的信任方法进行了全面调查。基于一种新颖的云边缘信任管理框架和基于双区块链结构的云交易模型,它识别了该领域的开放挑战并为该领域的未来研究指明了方向。本文对云计算系统中基于区块链的信任方法进行了全面调查。基于一种新颖的云边缘信任管理框架和基于双区块链结构的云交易模型,它识别了该领域的开放挑战并为该领域的未来研究指明了方向。
