“…|G|, |G T |, and Z p are bit lengths required to store an element in the respective finite group. Our theoretical storage costs are similar to the MABKS [17] scheme. However, our scheme has lower constant terms and has little relevance to the user attribute size.…”

Currently, cloud computing has become increasingly popular and thus, many people and institutions choose to put their data into the cloud instead of local environments. Given the massive amount of data and the fidelity of cloud servers, adequate security protection and efficient retrieval mechanisms for stored data have become critical problems. Attribute-based encryption brings the ability of fine-grained access control and can achieve a direct encrypted data search while being combined with searchable encryption algorithms. However, most existing schemes only support single-keyword or provide no ranking searching results, which could be inflexible and inefficient in satisfying the real world’s actual needs. We propose a flexible multi-keyword ranked searchable attribute-based scheme using search trees to overcome the above-mentioned problems, allowing users to combine their fuzzy searching keywords with AND–OR logic gates. Moreover, our enhanced scheme not only improves its privacy protection but also goes a step further to apply a semantic search to boost the flexibility and the searching experience of users. With the proposed index-table method and the tree-based searching algorithm, we proved the efficiency and security of our schemes through a series of analyses and experiments.

“…Many searchable attribute-based encryption schemes (ABS) [16][17][18][19][20][21][22][23][24] have provided fine-grained access control, dynamic updates, and attribute revocations. However, searching capabilities could be more potent in most schemes to fulfill actual needs.…”
