Attribute based signature (ABS) permits users produce signatures using any predicate of attributes issued from an attribute authority. ABS disallows any group of colluding users to forge a signature based on a predicate of attributes which they do not individually satisfy. Earlier schemes in this direction are either in the generic group model or support only single-level threshold predicates. In this paper, we propose the first attribute based signature schemes that support bounded flexible multi-level threshold predicates. Our first scheme is proved in the random oracle model and the second does not rely on random oracles. We provide security models for unforgeability and attribute-privacy and formally prove the same under the Computational Diffie-Hellman assumption.
