基于区块链的云问责制飞行数据记录器
A Blockchain-based Flight Data Recorder for Cloud Accountability
摘要：
许多公司依赖云基础设施来满足其计算、通信和数据存储需求。虽然云服务提供了一些好处，例如，用现收现付模式取代IT基础设施的高昂前期成本，也带来了众所周知的难以解决的严重问题。从本质上讲，云计算客户在他们无法直接控制的基础设施上存储数据和运行计算。因此，当出现问题时-违反服务水平协议，数据损坏，数据泄漏，安全漏洞-客户和云提供商都面临着就哪一方负责达成一致的挑战。在本文中，我们回顾了在云基础设施中实施问责制的挑战和要求，并认为智能合约和区块链技术可能会为负责任的云提供关键贡献。
英文摘要：
Many companies rely on Cloud infrastructures for their computation, communication and data storage requirements. While Cloud services provide some benefits, e.g., replacing high upfront costs for an IT infrastructure with a pay-as-you-go model, they also introduce serious concerns that are notoriously difficult to address. In essence, Cloud customers are storing data and running computations on infrastructures that they can not control directly. Therefore, when problems arise -- violations of Service Level Agreements, data corruption, data leakage, security breaches -- both customers and Cloud providers face the challenge of agreeing on which party is to be held responsible. In this paper, we review the challenges and requirements for enforcing accountability in Cloud infrastructures, and argue that smart contracts and blockchain technologies might provide a key contribution towards accountable Clouds.
