Partially policy hidden CP-ABE supporting dynamic policy updating [PDF]
Tongxin xuebao, 2015 Ciphertext-policy attribute-based encryption (CP-ABE) was considered to be appropriate for cloud storage.However,under traditional CP-ABE scheme which was limited in terms of the scale of the data and the quantities of the attributes,computation and ...

Efficient pairing-free CP-ABE based on ordered binary decision diagram [PDF]
Tongxin xuebao, 2019 To improve the computational efficiency of ABE,its access structure was optimized and a pairing-free CP-ABE scheme based on ordered binary decision diagram (OBDD) was proposed.Based on the elliptic curve cryptography,the complex bilinear pairing ...

Achieving Flexible and Self-Contained Data Protection in Cloud Computing
IEEE Access, 2017 For enterprise systems running on public clouds in which the servers are outside the control domain of the enterprise, access control that was traditionally executed by reference monitors deployed on the system servers can no longer be trusted.
