There are a lot of important and sensitive data in databases, which need to be protected from attacks. To secure the data, Cryptography support is an effective mechanism. However, a tradeoff must be made between the performance and the security because encryption and decryption greatly degrade the query performance. In this paper, a framework is proposed that can quickly implement query over encrypted...
the volume of data storage capacity has changed a lot as compared with earlier times. As most computers were standalone and only the users had access to data, security was not a big concern. All this changed when computers became linked in networks, in form of small dedicated networks to large LANs, WANs and the World Wide Web. With the growth of networking the security of data became a big issue...
Privacy preserving data mining of distributed data is an important direction for data mining, and privacy preserving clustering is one of the main researches. At present, most privacy preserving clustering algorithms are concentrated on k-means and based on two parties and a trusted third party, clustering results are uncertain and hard to find complex shape clusters, and the protocols are inefficient...
