상기와 같은 대칭키 기반의 암호 생성 및 검색 방법과 그 시스템을 이용하는 것에 의해, 색인의 크기를 최소화함으로써 저장공간 효율성을 증가시킬 수 있으며, 다중키워드 검색을 제공하여 빠르고 유연한 검색 쿼리가 가능하다.
Bloom filter (Bloom filter) by using the base indices for the encrypted data without the decoding process and to reduce the index size to the number of keywords symmetric key based on the password to retrieve the data via the generation and retrieval method and system relates to, a server, a user terminal and a keyword by the code generating means which is installed in the user terminal, the user to search from the user terminal and the server, the trapdoor information is not leaked to the keywords between the communication between the server a password generating method of a symmetric key based on that disables learning, (a) transmitting the encrypted data key in the user terminal is the own known to the server, (b) data from said password generating means are indexing and index to put a search key that is used to search for the pseudo-random number permutation to produce the keys that are used in the pseudo-random number function and (c) said password generating means wherein the keyword corresponding to each document in the respective pseudo-random number function (b ) by applying with the generated keys from step to provide a configuration that includes generating an index to the bloom filter method.
And the like by using a symmetric key based on a password, and search method and system, by minimizing the size of an index can increase the storage efficiency, it is possible to fast and flexible search query by providing multiple search keywords.
