| description | Aiming at the problem of data island caused by high-sensitivity data in the cloud,which makes the data unable to search,discover and share with each other,a distributed privacy protection data search scheme is proposed to realize the two-way confidentiality of data and search conditions in distributed scenarios,and a trusted search certificate could be established.Firstly,the data model,the objectives and application scenarios of scheme protection are defined.Next,the design framework and protocol flow of the scheme are proposed,focusing on the overall flow of three parts:trusted data interaction channel based on blockchain,trusted key sharing module and ciphertext search engine.Then,a full-text search engine tantivy SGX in ciphertext state based on trusted execution environment is proposed,and the principle and implementation method are analyzed in detail.Finally,the overall process and core methods are implemented and verified.Experiments show that the scheme is efficient and feasible,and can effectively enhance the security of data discovery and search in distributed environment. |
