Email this article An integrated access tree construction and tree encryption to improve the encryption/decryption efficiency
Abstract
This work proposes a useful Ciphertext-Policy Attribute-Based Hierarchical archive grouping Encryption plan named CP-ABHE. By sensible, we infer that CP-ABHE is progressively powerful in both calculation and additional room without surrendering information security. In CP-ABHE, we initially build up a ton of composed access trees subject to the chronicles' attribute sets. We use the insatiable procedure to create the trees bit by bit and build up the trees capably by joining the little ones. By then, all the reports on an organized access tree are encoded together. Particular to existing plans, the leaves in different access trees with a comparative trademark offer a comparable mystery number, which is used to scramble the archives. This fundamentally improves the presentation of CP-ABHE. The security of our arrangement is speculatively exhibited subject to the decisional bilinear Diffine Hellman supposition.
