Attrapadung (Eurocrypt 2014) proposed a generic framework called pair encoding to simplify the design and proof of security of CPA-secure predicate encryption (PE) in composite order groups. Later Attrapadung (Asiacrypt 2016) extended this idea in prime order groups. Yamada et al. (PKC 2011, PKC 2012) and Nandi et al. (ePrint Archive: 2015/457, AAECC 2017) proposed generic conversion frameworks to achieve CCA-secure PE from CPA-secure PE provided the encryption schemes have properties like…

This paper proposes the first generic framework for attribute-based encryptions (ABE) with master-secret-key-dependentmessage security (mKDM security) for affine functions via predicate encodings by Chen, Gay and Wee and obtains a set of new mKDM-secure ABE schemes with high expressiveness that have never been reached before.

Predicate signatures from pair encodings via dual system proof technique

- Computer Science, MathematicsJ. Math. Cryptol.

The author shows that if the underlying pair encoding scheme is either perfectly secure or computationally (doubly-selectively) secure, then the PE scheme will be fully secure.

Generic Negation of Pair Encodings

- Computer ScienceIACR Cryptol. ePrint Arch.
- 2021

A generic transformation that takes any pair encoding scheme (PES) for a predicate P and produces a PES for its negated predicate P is proposed, which finally solves a problem that was open since 2015 and provides the first pair encode scheme for negated doubly spatial encryption.

Tag-based ABE in prime-order groups via pair encoding

- 2021

A ciphertext-policy scheme for non-monotone span programs with compact ciphertexts satisfying semi-adaptive security if pair encoding schemes satisfy perfect security (resp. relaxed perfect security) from the standard k-linear assumption is proposed.

Dual System Encryption Framework in Prime-Order Groups via Computational Pair Encodings

A new generic framework for achieving fully secure attribute based encryption (ABE) in prime-order bilinear groups is proposed and the first generic implication from ABE for monotone span programs to ABE for branching programs is established.

Generic Conversions from CPA to CCA secure Functional Encryption

- Computer Science, MathematicsIACR Cryptol. ePrint Arch.

Different ways of obtaining CCA-secure functional encryptions of almost all categories are provided, provided the underlying CPA-secure encryption scheme has either restricted delegation or verifiability feature and it is observed that almost all functional encryption schemes have this feature.

Generic Constructions for Chosen-Ciphertext Secure Attribute Based Encryption

This paper exhaustively checks the verifiability of existing ABE schemes and found that most of them satisfy such a property, hence CCA-secure versions of these schemes can be obtained automatically.

By combining the proposed frameworks for PS and PE, this work provides a generic construction for predicate signature (PS) from the pair encoding schemes, which achieves the perfect privacy, and the strong unforgeability and CCA security in the adaptive-predicates model.

The CPA to CCA conversion for PE is revisited and a new conversion based on verifiability is proposed, which generalizes the existing conversion and works irrespective of the number of components in the system-indices.

Converting Pairing-Based Cryptosystems from Composite-Order Groups to Prime-Order Groups

An abstract framework is developed that encompasses the key properties of bilinear groups of composite order that are required to construct secure pairing-based cryptosystems, and a security theorem is given for the prime-order group instantiation of each system.

A new simple property for pair encodings called symbolic security is proposed, which is inherently tied to the security of predicate encryption schemes by arguing that any scheme which is not trivially broken must satisfy it.

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,…
