摘要/Abstract

摘要：

云存储服务的一种主要收费模式为依据服务提供商度量的客户资源实际使用量进行计费。因此，支忖方和服务提供商之间的信任问题成为这种商业计费模式的关键因素，并可能引发安全问题。一方面，云存储服务提供商或者内部人员可能声称更多的客户资源使用量而多收取服务费用；另一方面，支忖方可能否认已使用的资源从而减少应支忖的费用。提出了一种基于散列链的资源使用度量机制，对不同资源分别产生可验证的证据。对于多数资源，现有云存储计费机制可以依据资源使用总量产生证据，但是考虑到存储量随时间不断波动并且资源的计费不仅与存储量相关还与时间因素相关，因此现有机制不能完全适用。提出的存储资源使用度量机制同时考虑时间和存储量2个因素，利用与计费方式关联的散列链产生证据，实现了原有机制的改进，达到了资源使用的可验证度量目标。

Abstract:

Cloud storage is a pay-per-use service of which the billing plan is typically based on users' resource consump-tion metered by server side. Therefore, the trustworthiness between payer and service provider becomes a key factor for the business, and triggers security concerns. On the one hand, service providers or insiders may inflate the amount of re-source consumed to get more service charge. On the other hand, payers may deny the resource consumption to pay less. Thus, a resource metering and accounting scheme based on hash chain was proposed. It generated verifiable proof for different types of resources. For most resources, proof can be generated based on total amount of resource incurred. How-ever, similar scheme cannot be applied to storage space usage, since it fluctuates and the billing relies on not only the utilized storage space but also the storage duration. The proposed storage usage metering scheme considers time factor together with storage space, and generates proof according to the diverse storage billing plans. It improves previous schemes, and achieves the goal of verifiable metering and accounting.
