| 摘 要： | 针对实际密文数据库的应用,在全文检索倒排索引技术的基础上,设计了一种通过密文倒排索引文件对其进行快速检索的方法。密文索引文件中主要包含有索引项、相对应的记录主键等信息。检索时,通过用检索词匹配索引文件中的索引项,找到对应的记录主键集合,再根据记录主键集合查询密文数据库,获取相应的密文数据,进行解密即可获取明文数据信息。整个检索过程中不对数据库进行解密,从而实现了在不解密的情况下对密文数据库的快速检索。

| Abstract: | Base on the inverted index technology of full search,this paper focused on the application of encrypted database,designed a method which can retrieval the encrypted database through ciphertext inverted index file.Ciphertext index file contains an index entry,the corresponding records of the primary key and other infomation.By using |

| Keywords: | to match index entry of the index files it can find the corresponding primary key set get the corresponding ciphertext data by querying encrypted database according to the primary key set then obtain the plaintext data information after decryption As the whole retrieval process does not decrypt the database it achieved quick query on the encrypted database without decryption Key words：Encrypted Database Inverted Index Query on Ciphertext |
