基于 SHA-3的密文数据检索技术
A CIPHERTEXT DATA RETRIEVAL TECHNOLOGY BASED ON SHA-3
摘要
Abstract
Research and application of SHA-3 algorithm has become the focus in current academic studies.Aiming at the low efficiency problem of existing ciphertext retrieval system and on the basis of analysing and studying the existing ciphertext data retrieval technology, we use AES-128 and SHA-3 algorithms to design and implement an SHA-3-based ciphertext data retrieval system.Experiments prove that the system can realise database encryption, precise ciphertext retrieval and fuzzy ciphertext retrieval, improves the efficiency of ciphertext retrieval and guarantees the safety of the database.The use of twice retrieval model and SHA-3 algorithm makes the retrieval accuracy and efficiency of the system reaches 70%of the plaintext retrieval without index.关键词
