摘要

与其他行业一样,银行系统向云的迁移在不久的将来似乎是不可避免的。通过利用云技术,任何客户的个人和财务数据都可以被第三方服务提供商访问和控制。然而,为了保持机密性,这些信息应该以加密格式保存,这对搜索等基本操作的有用性和灵活性有影响。此外,在金融机构中,数据所有者可能希望为来自不同领域的用户提供搜索功能。因此,为了提供这种灵活性,引入了一个多权威细粒度搜索系统,其中每个权威管理单个但完全不相交的属性域。因此,该系统具有更强的可扩展性,可以处理来自不同领域的大量用户并有效地管理他们的凭据。然而,文献中的大多数方案缺乏此特性,并且由于单一的集中可信权威而存在性能瓶颈。

Multi-Authority Fine-Grained Data Sharing and Search Scheme for Cloud Banking Systems
The migration of the banking system to the cloud seems inevitable in near future like any other industry. By leveraging cloud technology, the personal and financial data of any customer can be accessed and controlled by third-party service providers. However, in order to maintain confidentiality, this information should be kept in an encrypted format, which has an impact on the usefulness and flexibility of fundamental operations like search. Moreover, in a financial institution, a data owner may want to provide the searching capability to the users from diverse domains. Therefore, to provide such flexibility, a system of multi-authority fine-grained search is introduced where each authority manages a single but entirely disjoint domain of attributes. As a result, the proposed system is more scalable, it can handle a large number of users from diverse domains and manage their credentials effectively. While most of the schemes in the literature lack this feature, and have a performance bottleneck because of a single centralized trusted authority.
