    Attribute-Based Signatures (ABS) is a versatile primitive which allows an entity to sign a message with fine-grained control over identifying information. A valid ABS only attests to the fact that A single user, whose attributes satisfy the predicate, has endorsed the message . While ABS has been well investigated since its introduction, it is unfortunate that key exposure-an inherent weakness of digital signatures-has never been formally studied in the scenario of ABS. We fill this gap by proposing a new notion called forward secure ABS, its formal security models and a generic (also the first) design based on well established crypto primitives.
