| Abstract: | To resolve the shortcomings in the application process of ciphertext retrieval system, such as the security, the efficiency of retrieval, redundancy and less friendly to users, this paper first proposed an improved ciphertext index build strategy and a ranked method of ciphertext retrieval based on histo- ry by analyzing and researching the existing ciphertext retrieval. Then the ciphertext retrieval system had been designed and implemented. The test results showed the system had improved the efficiency of retrieval and guaranteed the security of the system, meanwhile, the retrieval results were more friend- ly to users. |
