Research on parallel crypt inverted index
摘要
Abstract
Encrypting data is a method to protect customer’s privacy, especially in the open system, but it becomes a problem how to do query on encrypted data. In view of some low performance of the existing SSE-1 scheme, it uses dif-ferent encryption strategies to design a crypt inverted index(Crypt-Lucene)based on lucene. In addition, a scheme for building Crypt-Lucene parallelly is proposed based on MapReduce. The performance of the scheme is analyzed in the theory, and then experiments are conducted to demonstrate the efficiency of the design. The experimental results show that it can reduce 60%time to build index with Crypt-Lucene compared with SSE-1, and it also gets a good space performance. It is observed that building 8 Crypt-Lucene for large document collections with MapReduce on the Hadoop cluster consisting of four nodes can reduce 83.4%time.关键词
