We provide a functional encryption system that supports functionality for regular languages. In our system a secret key is associated with a Deterministic Finite Automata (DFA) M....
Abstract. Recently, cryptographic access control has received a lot of attention, mainly due to the availability of efficient Attribute-Based Encryption (ABE) schemes. ABE allows ...
We construct an Attribute-Based Encryption (ABE) scheme that allows a user’s private key to be expressed in terms of any access formula over attributes. Previous ABE schemes wer...
A well-known concern in the setting of identity based encryption is that the PKG is all powerful and has to be completely trusted. To mitigate this problem, the notion of Accounta...
