中文摘要：

数据的不断增长推动了云计算、云存储的发展,大量数据被存储到云端,数据的不断积累占据了太多存储空间.为了节省空间,重复数据删除技术被提出并广泛使用.在原始信息锁加密的基础上进行改进,引入布隆过滤器来实现重复检测,继而完成安全存储.对方案性能进行分析后发现,可以实现基本的安全机密性,并降低了计算开销.

英文摘要：

The fast growth of data promotes the development of cloud computing and cloud stor- age, so a large amount of data is stored in the cloud, and the accumulation of data occupies too much storage space. In order to save space, data deduplication technology is proposed and widely used. Based on the original message-lock encryption（MLE） ,bloom filtering is used to achieve the duplicate detection then complete the safety storage. The performance of scheme is analyzed, which can achieve basic security and confidentiality and reduces the computational overhead.
