Short Attribute-Based Signatures for Threshold Predicates
[chapter]
2012
Lecture Notes in Computer Science
Attribute-based cryptography is a natural solution for fine-grained access control with respect to security policies. In the case of attribute-based signatures (ABS), users obtain from an authority their secret keys as a function of the attributes they hold, with which they can later sign messages for any predicate satisfied by their attributes. A verifier will be convinced of the fact that the signer's attributes satisfy the signing predicate while remaining completely ignorant of the identity
