Attribute-based encryption

The concept of attribute based encryption was introduce by Amit Sahai and Brent Waters in 2004^[1]. It is a type of public-key encryption in which the public key of a user and the ciphertext are dependent about attributes (e.g. the country he lives, the kind of subscritpion he has, ...). In a such system, The decryption of a ciphertext is possible only if the set of attributes of the user key matches the attributes of the ciphertext.
