Attribute-based encryption provides good solutions to the problem of anonymous access control by specifying access policies among private keys or ciphertexts over encrypted data. In ciphertext-policy attribute-based encryption (CP-ABE), each user is associated with a set of attributes, and data is encrypted with access structures on attributes. A user is able to decrypt a ciphertext if and only if...
As a new public key primitive, attribute-based encryption (ABE) is envisioned to be a promising tool for implementing fine-grained access control. When applying ABE schemes to practical applications, revocation mechanism is very necessary for any ABE schemes involving many users. Revocation for ABE schemes is a challenge issue since each attribute is conceivably shared by multiple users. Revocation...
