| 摘 要： | 从云存储实际需求出发，设计了一个云存储环境下支持用户隐私保护和用户属性撤销的多属性权威的属性加密机制，为了保证系统实现的效率和减轻数据持有者的负担，在属性撤销中，复杂的计算任务都委托给可信第三方或云服务器完成。所提方案在DBDH假设下被证明是安全的。

| Abstract: | Based on the actual demands of cloud storage system,a new multi-authority ABE (MA-ABE) scheme is constructed to support user privacy protection and attribute revocation.For enhancing efficiency and alleviatingowner’s computing load，the complex computing works involved in attribute revocation are delegated to a trusted third party orcloud server.The proposed scheme is provably secure under the DBDH assumption. |

| Keywords: | cloud storage attribute based encryption multi-authority privacy protection attribute revocation |
