Fully Secure Functional Encryption: Attribute-Based Encryption and (Hierarchical) Inner Product Encryption
TLDR
We present two fully secure functional encryption schemes for two cases of functional encryption, namely attribute-based encryption (ABE) and predicate encryption (PE) for inner-product predicates. Expand

Fully Secure Functional Encryption with General Relations from the Decisional Linear Assumption
TLDR
This paper presents a fully secure functional encryption scheme for a wide class of relations, that are specified by nonmonotone access structures combined with inner-product relations. Expand

Reducing elliptic curve logarithms to logarithms in a finite field
TLDR
We demonstrate the reduction of the elliptic curve logarithm problem to the logarithsm problem in the multiplicative group of an extension of the underlying finite field. Expand

How to Enhance the Security of Public-Key Encryption at Minimum Cost
TLDR
This paper presents a simple and efficient conversion from a semantically secure public-key encryption scheme against passive adversaries to a non-malleable one against adaptive chosen-ciphertext attacks (active adversaries) in the random oracle model. Expand

Hierarchical Predicate Encryption for Inner-Products
TLDR
This paper presents a hierarchical predicate encryption scheme for inner-product predicates that is secure (selectively attribute-hiding) in the standard model under new assumptions. Expand

REACT: Rapid Enhanced-Security Asymmetric Cryptosystem Transform
TLDR
This paper presents REACT, a new conversion which applies to any weakly secure cryptosystem, in the random oracle model: it is optimal from both the computational and the security points of view. Expand
