Abstract

Working in various service models ranging from SaaS, PaaS, to IaaS, cloud computing is a new revolution in IT, and could reshape the business model of how the IT industry works today. Storage services are a fundamental component of the cloud computing paradigm. By exploiting the storage services, users outsource their data to the cloud so as to enjoy the reduced upfront maintenance and capital costs. However, a security challenge associated with data outsourcing is how to prevent data abuses by the cloud. It has been commonly accepted that data encryption offers a good solution to this problem. With data encryption, an issue arises when the data owner who outsourced the data wants to revoke some data consumers' access privileges, which normally involves key re-distribution and data re-encryption. In this work, we propose a generic scheme to enable fine-grained data sharing over the cloud, which does not require key-redistribution and data re-encryption whatsoever. The main primitives we make use of are attribute-based/predicate encryption and proxy re-encryption, but our construction is not restricted to any specific scheme of its kind. Our scheme has a number of advantages over other similar proposals in the literature.
云环境下安全数据共享的通用方案
在从SaaS、PaaS到IaaS的各种服务模型中工作,云计算是IT领域的一场新革命,并可能重塑当今IT行业工作方式的业务模型。存储服务是云计算范式的基本组成部分。通过利用存储服务,用户将其数据外包给云,从而减少前期维护和资本成本。然而,与数据外包相关的一个安全挑战是如何防止云滥用数据。人们普遍认为数据加密是解决这个问题的一个很好的方法。对于数据加密,当外包数据的数据所有者想要撤销某些数据消费者的访问特权时,就会出现问题,这通常涉及密钥重新分发和数据重新加密。在这项工作中,我们提出了一个通用方案来实现云上的细粒度数据共享,它不需要密钥重新分配和数据重新加密。我们使用的主要原语是基于属性/谓词的加密和代理重新加密,但是我们的构造并不局限于其类型的任何特定方案。与文献中其他类似的建议相比,我们的方案有许多优点。
