ABE provides a secure and automatic way to enforce access control, but access control may not involve encryption. In the ABE setting, the resources (that one wants to access) are encrypted by a "controller" and then the ciphertexts are made public and each user is granted a key corresponding to its specific access right. Then, the controller doesn't need ...

Attribute-Based Encryption (ABE) schemes are a way to securely send (i.e share) a plaintext (message) amongst some particular receivers. The data owner (sender) consider an access policy to encrypt the message under this policy that a data user (receiver) is able to decrypt the ciphertext if and only if he/she satisfies the policy. So the ABE schemes just ...
