WebAbstract. Ciphertext-policy attribute-based encryption (CP-ABE) is an access control mechanism where a data provider encrypts a secret message and then sends the ciphertext to the receivers according to the access policy which she/he decides. If the attributes of the receivers match the access policy, then they can decrypt the ciphertext.

Web3 A CP-ABE system with the non-monotonic access structure We construct a CP-ABE scheme which supports the use of positive and negative attributes. Our construction is built on Bethencourt et al.’s work [1] and Ostrovsky et al.’s [13] work. Speciﬁcally, we modify Bethencourt et al.’s CP-ABE construction to accommodate a non-monotonic WebIn CP-ABE, the ciphertext is associ-ated with an access policy and the user key is labeled with a set of attributes. Since its inception, CP-ABE has attracted a lot of attention for fine-grained access control in cloud environments. In [10–16], different CP-ABE schemes are proposed for fine-grained access control of data in the cloud. i am baton rouge

WebBased on the CP-ABE scheme proposed by Lewko et al. [14] recently, we present an eﬃcient construction of CP-ABE with partially hidden access structures.
