In recent years, attribute-based encryption (ABE) provides a new idea to help researchers solving the problem of data privacy protection in cloud. But there are two issues in traditional ABE, the first issue is that the attributes in the access structures will be sent to users in cleartext together with the ciphertext. So a attacker has the opportunity

In the context of Ciphertext-Policy Attribute-Based Encryption (CP-ABE), if a decryption device associated with an attribute set S_D appears on eBay, and is alleged to be able to decrypt any ciphertexts with policies satisfied by S_D, no one including the CP-ABE authorities can identify the malicious user(s) who build such a decryption device using ...

Multiple-authority-keys CP-ABE
2011 IEEE 3rd International Conference on Communication Software and Networks, 2011Functional encryption provides more sophisticated and flexible relations between the encryption-key and decryption-key. Previous FE systems only allow for functionalities that take in a single authority key and plaintext as inputs. In this paper, a Multiple-Authority-Keys Attribute-Based Encryption system is presented.

An Attribute Revocable CP-ABE Scheme
2019 Seventh International Conference on Advanced Cloud and Big Data (CBD), 2019Ciphertext storage can effectively solve the security problems in cloud storage, among which the ciphertext policy attribute-based encryption (CP-ABE) is more suitable for ciphertext access control in cloud storage environment for it can achieve one-to-many ciphertext sharing. The existing attribute encryption scheme CP-ABE has problems with revocation

An Expressive Hidden Access Policy CP-ABE
2017 IEEE Second International Conference on Data Science in Cyberspace (DSC), 2017Ciphertext Policy - Attribute Based Encryption (CPABE) has emerged as a feasible solution to address challenges of access control to a diverse set of users. In CP-ABE, owner encrypts its data under a policy of attributes, while any data consumer satisfying it can decrypt the data.

OE-CP-ABE: Over-Encryption Based CP-ABE Scheme for Efficient Policy Updating
2017Ciphertext-Policy Attribute Based Encryption (CP-ABE) is a promising technique to enable fine-grained access control for data storage and sharing. In CP-ABE, data are encrypted with an access policy on attributes, so the frequent policy updating has always been a challenging issue for data owners.
