Key-Policy Attribute-Based Encryption for Boolean Circuits from Bilinear Maps

چکیده
We propose the first Key-policy Attribute-based Encryption (KP-ABE) scheme for (monotone) Boolean circuits based on bilinear maps. The construction is based on secret sharing and just one bilinear map, and can be viewed as an extension of the KP-ABE scheme in [7]. Selective security of the proposed scheme in the standard model is proved, and comparisons with the scheme in [5] based on leveled multilinear maps, are provided. Thus, for Boolean circuits representing multilevel access structures, our KP-ABE scheme is more efficient than the one in [5].

Efficient Key-policy Attribute-based Encryption for General Boolean Circuits from Multilinear Maps
We propose an efficient Key-policy Attribute-based Encryption (KP-ABE) scheme for general (monotone) Boolean circuits based on secret sharing and on a very particular and simple form of leveled multilinear maps, called chained multilinear maps. The number of decryption key components is substantially reduced in comparison with the scheme in [6], and the size of the multilinear map (in terms of ...
متن کاملA Key-Policy Attribute-based Encryption Scheme for General Circuit from Bilinear Maps
By access structure and attribute set, attribute-based encryption realizes fine-grained access control and one to many encryption. The expression of access structure directly decides the application range of one scheme and the general circuit reaches the best form. Since the safety of multilinear maps is suffered question, using relatively efficient and safe bilinear maps to construct circuit a...
متن کاملFunctional Encryption for Regular Languages
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 . A ciphertext CT encrypts a message m and is associated with an arbitrary length string w. A user is able to decrypt the ciphertext CT if and only if the DFA M associated with his private key accepts the string w. Com...
متن کاملAttribute-Based Encryption for Circuits from Multilinear Maps
In this work, we provide the first construction of Attribute-Based Encryption (ABE) for general circuits. Our construction is based on the existence of multilinear maps. We prove selective security of our scheme in the standard model under the natural multilinear generalization of the BDDH assumption. Our scheme achieves both Key-Policy and Ciphertext-Policy variants of ABE. Our scheme and its ...
متن کاملFully Secure and Succinct Attribute Based Encryption for Circuits from Multi-linear Maps
We propose new fully secure attribute based encryption (ABE) systems for polynomialsize circuits in both key-policy and ciphertext-policy flavors. All the previous ABE systems for circuits were proved only selectively secure. Our schemes are based on asymmetric graded encoding systems in composite-order settings. The assumptions consist of the Subgroup Decision assumptions and two assumptions w...
