Study of Streamline Dynamic Successive Trees Index Model for Ciphertext

Abstract:

Secure index is the core technology in the full-ciphertext retrieval. In order to appliance the efficient full-text retrieval in the ciphertext state, a streamline dynamic successive trees of ciphertext(SDSTC)index model is proposed. The SDSTC index model which supports queries of substring and dynamic updating of index, has a high recall and precision ratio in retrieval. Giving algorithms of model index creation, retrieval and ciphertext index updating and the analysis of its security and efficiency. Compared with other existing index models, experiments show that the SDSTC index model has good time efficiency and more suitable for areas of ciphertext security of full-text retrieval
