Distributed Privacy Protection Data Search Scheme by LIU Ming-da, SHI Yi-juan, RAO Xiang, FAN Lei

“…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.…”

Privacy-preserving Hamming and Edit Distance Computation and Applications by DOU Jia-wei

“…With the rapid development of information technology,privacy-preserving multiparty cooperative computation is becoming more and more popular.Secure multiparty computation is a key technology to address such problems.In scientific research and practical applications,people measure the similarity of two strings with Hamming(edit) distance.It is of great significance to study privacy-preserving Hamming(edit) distance computation.This paper studies privacy-preserving Hamming(edit) distance computation.First,we transform Hamming distance computation to inner product computation of vectors,and then use Okamoto-Uchiyama(OU) cryptosystem and encryption-and-choose technique to design protocol for Hamming distance.Second,we give each alphabet of a string a number,transform edit distance to determine whether the difference of the number of two alphabets is 0,and use OU cryptosystem to design a privacy-preserving edit distance computation protocol.The security of the protocol is strictly proved,the computational complexity of the protocol is analyzed,the actual implementation efficiency of the protocol is tested and compared with the existing results.Theoretical analysis and experimental results show that our protocols are efficient.…”
