Access Control Encryption for Equality, Comparison, and More [chapter]

Georg Fuchsbauer, Romain Gay, Lucas Kowalczyk, Claudio Orlandi
2017 Lecture Notes in Computer Science  
Access Control Encryption (ACE) is a novel paradigm for encryption which allows to control not only what users in the system are allowed to read but also what they are allowed to write.  ...  In this work we answer the question in the affirmative by giving (efficient) constructions of ACE for an interesting class of predicates which includes equality, comparison, interval membership, and more  ...  We would like to thank the reviewers of PKC'17 for their diligent proofreading and valuable remarks, helping us to improve the paper.  ...
