Generic Transformations of Predicate Encodings: Constructions and Applications
Predicate Encryption Attribute-Based Encryption Predicate Encodings
2016/12/7
Predicate encodings are information-theoretic primitives that
can be transformed generically into predicate encryption schemes for a
broad class of predicates (Wee, TCC 2014; Chen, Gay, Wee, EUROCRY...
We introduce the notion of predicate encodings, an information-theoretic primitive reminiscent
of linear secret-sharing that in addition, satisfies a novel notion of reusability. Using this notion, w...
Improved Dual System ABE in Prime-Order Groups via Predicate Encodings
public-key cryptography attribute-based encryption
2015/12/31
We present a modular framework for the design of efficient adaptively secure attribute-based encryption
(ABE) schemes for a large class of predicates under the standard k-Lin assumption in prime-orde...
