Random information on the term “ABE”:
Attribute-based encryption is a type of public-key encryption in which the secret key of a user and the ciphertext are dependent upon attributes (e.g. the country in which he lives, or the kind of subscription he has). In such a system, the decryption of a ciphertext is possible only if the set of attributes of the user key matches the attributes of the ciphertext.
A crucial security aspect of attribute-based encryption is collusion-resistance: An adversary that holds multiple keys should only be able to access data if at least one individual key grants access.
The concept of attribute-based encryption was first proposed by Amit Sahai and Brent Waters  and later by Vipul Goyal, Omkant Pandey, Amit Sahai and Brent Waters. Recently, several researchers have further proposed Attribute-based encryption with multiple authorities who jointly generate users’ private keys.
There are mainly two types of attribute-based encryption schemes: Key-policy attribute-based encryption (KP-ABE) and ciphertext-policy attribute-based encryption (CP-ABE).
