Abstract To deal with the key-exposure protection problem in attribute-based signature systems, we extend the parallel key-insulated mechanism to attribute-based signature scenarios, and then introduce the primitive of an Attribute-Based Parallel Key-Insulated Signature (ABPKIS). After formalizing the definition and security notions for ABPKIS, a concrete ABPKIS scheme is presented. The security of our proposed ABPKIS scheme can be proved on a standard model. According to our knowledge, this is the first ABPKIS scheme up to now. Moreover, this is also the first concrete attribute-based key-insulated signature construction supporting multi-helpers.
