可搜索对称加密技术在气象数据安全领域的研究与进展
Research and Development of Searchable Symmetric Encryption Schemes for the Security of Meteorological Data
中文摘要：
与传统存储模式相比，云存储技术运维成本低廉，服务模式更为弹性可靠，已成为目前应用最广泛的信息技术之一。随着数据采集方式的多样化,数据总量呈指数级增长，数据的隐私泄露问题成为云存储技术发展的重要制约。把数据加密处理后再存储在云服务方，可以有效解决隐私泄露问题，但却给数据的检索和查询带来额外的通信、存储和计算成本。现有的解决方案无法解决用户对多源气象数据的加密搜索需求，因此不能直接应用于气象数据云存储应用中。为了解决该问题，提出了一种新型且安全高效的可搜索对称加密方案。该方案不仅可以满足用户对多数据源数据的加密和检索需求，而且可以保证敌手无法获取用户文档和搜索结果在各数据源中的分布信息，因而可以有效保证用户数据的隐私安全。

Abstract：
Compared to the traditional storage pattern, user can effectively reduce the cost of data storage and management by outsourcing data to cloud storage, and enjoy the advantages of cloud storage such as high scalability and management. Researchers have paid much more attentions on this issue, which is one of the most widely applications and techniques in recent years. Data security has become a recognized issue. Using users’ own private key to encrypt their own data before outsourcing is an effective way to avoid data private leakage, but it will destroy the query capability of data, and bring much more communication cost, storage and computation overhead. The existing searchable symmetric encryption schemes may solve this problem, but it only can be applied to one single data source. Meteorological data is the scarce and valuable resources in meteorology departments, so we should pay much more attentions to the data protection issues.Here, we propose a novel scheme, which may be applied to multiple data sources and has a high-performing. The test results show the our scheme may provide efficiently search query result without leaking users’ information and query information.
