Revocable Attribute-Based Signatures With Adaptive Security in the Standard Model

Date Added: Jan 2011

An attribute-based signature with respect to a signing policy, chosen ad-hoc by the signer, convinces the verifier that the signer holds a subset of attributes satisfying that signing policy. Ideally, the verifier must obtain no other information about the identity of the signer or the attributes he holds. This primitive has many applications in real scenarios requiring both authentication and anonymity/privacy properties.
