Abstract:

There are some limitations regarding efficiency, security and so on in the classic ABE scheme. To address these problems, researchers extended the classic ABE scheme on different aspects to satisfy the requirements of various applications. In this paper, we first introduce the mechanism of ABE. Then, we discuss the researches of ABE on the aspects of efficiency improvement, policy hiding, permission revocation and security enhancement. Finally, we provide an outlook of the potential future research directions of ABE.

Key words: attribute-based encryption, efficiency improvement, policy hiding, permission revocation, security enhancement
