Ciphertext 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. Problem of existing CP-ABE schemes is that the access matrix is sent in plaintext along with the ciphertext. Hence, to...
As a promising cryptographic primitive, attributebased encryption (ABE) is adopted to protect outsourced data. However, there are some issues in existing attribute-based encryption schemes. First, the attribute authority manages attributes of users, so it may cause the leakage of users' privacy information. Second, because the access structures are directed along with the ciphertexts and may violate...
