Security and Privacy in the Cloud

云计算代表了近年来发展最快的计算模式之一，因为它可以通过互联网为用户和组织提供动态、可扩展、经济高效的基础设施、平台和软件访问。 云存储是云计算范式实现的关键服务之一，它允许用户不仅将这些类型的服务用于归档和备份目的，而且还用于日常存储。这使得从各种平台和位置轻松访问数据，以及将与数据管理相关的复杂性从用户转移到服务提供商。此类基础设施的一个关键障碍是确保云存储提供商及其客户拥有足够的安全性和隐私，同时提供可接受的维护、可用性和处理水平。这项提议侧重于对云存储的三个主要领域做出关键贡献：高效的数据存储、远程存储内容的私人搜索以及数据完整性及其可检索性的保证。

Cloud computing represents one of the fastest growing computing paradigms in recent years, as it can provide users and organizations dynamic, scalable, cost-effective access to infrastructure, platforms, and software over the internet. Cloud storage is one of the key services enabled by the cloud computing paradigm which allows users to use these types of services not only for archiving and backup purposes, but also for everyday storage. This enables ease of access to data from various platforms and locations, as well as moving complexities associated with data management from users to service providers. A key obstacle to such infrastructures is ensuring adequate security and privacy for both cloud storage providers and their clients, while providing acceptable levels of maintenance, availability, and processing. This proposal focuses on making key contributions to three major areas in cloud storage: efficient storage of data, the private search of remotely stored content, and the assurance of data integrity and its retrievability.
