Secure Search Algorithm for Conjunctive Keyword in Encrypted Data
Xingyi Liu · Jisuanji gongcheng · 2009
Existing keyword search algorithms can only deal with single keyword and presenting high time complexity. Aiming at this problem, this paper proposes a secure search algorithm for encrypted data which searches several conjunctive keywords at the same time. This algorithm partitions the processes for generating Capability into two parts——online part and offline part. Its run time of secure search is about eighty percents less than existing algorithms. Example analysis results show that this algorithm is reasonable and effective.
