中文密文数据库正则查询的研究与实现
Research and implement of regular query of chinese encrypted database
摘要
Abstract
In order to make the query of Chinese encrypted database more flexible, more convenient and more efficient, a new encrypted index is desigued. To support regular query, it registers the locations of a Chinese character in the records and registers the positions in a record field. Based on this index, a series of algorithms are presented for processing regular query, which make use of the information about the positions of Chinese characters to find out the records satisfying the query. Experiments show that this kind of index and algorithms can support regular queries of Chinese Encrypted database and has good query performance.关键词
