Multi-keyword searchable encryption scheme based on dynamic cuckoo filter
Existing solutions have utilized Cuckoo Filter(CF)on the server side to achieve multi-keyword searching.The capacity of CF is preset,which can not satisfy the continuous growth of the capacity expansion demand on the server side.To solve the above problems,a dynamic multi-keyword searchable encryption(DMKSE)was proposed,which used the dynamic cuckoo filter to solve the server-side capacity expansion demand,and improved the storage of document-keyword pairs,which improved the space utilization of the server-side,without additional time overhead.Experimental results show that DMKSE improves space utilization by at least 1.3481 times over the original scheme.
