Attribute-based encryption (ABE) was first introduced by Sahai and Waters [1] where the decryption ability of a user is based on his attributes. Later, it was divided into ciphertext-policy ABE (CP-ABE) and key-policy ABE (KP-ABE) [2]. In CP-ABE, a secret key is associated with user attributes and a ciphertext is associated with a boolean formula; a user… CONTINUE READING
