A keyword searchable attribute-based encryption scheme with attribute update for cloud storage. [PDF]
PLoS ONE, 2018 Ciphertext-policy attribute-based encryption (CP-ABE) scheme is a new type of data encryption primitive, which is very suitable for data cloud storage for its fine-grained access control.

Attribute‐based encryption implies identity‐based encryption [PDF]
IET Information Security, 2017 In this study, the author formally proves that designing attribute‐based encryption schemes cannot be easier than designing identity‐based encryption schemes. In more detail, they show how an attribute‐based encryption scheme which admits, at least, and policies can be combined with a ...

Revocable attribute-based proxy re-encryption
Journal of Mathematical Cryptology, 2021 Attribute-based proxy re-encryption (ABPRE), which combines the notions of proxy re-encryption (PRE) and attribute-based encryption (ABE), allows a semi-trusted proxy with re-encryption key to transform a ciphertext under a particular access policy into ...

Attribute-Based Functional Encryption on Lattices [PDF]
, 2013 We introduce a broad lattice manipulation technique for expressive cryptography, and use it to realize functional encryption for access structures from post-quantum hardness assumptions. Specifically, we build an efficient key-policy attribute-based encryption scheme, and prove its security in the selective sense from learning-with-errors ...

A Function Private Attribute-Based Encryption
International Journal of Distributed Sensor Networks, 2014 The function privacy notion was proposed by Boneh, Raghunathan, and Segev in August 2013. It guarantees that the secret key reveals nothing to malicious adversary, beyond the unavoidable minimal information such as the length of ciphertext.

ABE Squared: Accurately Benchmarking Efficiency of Attribute-Based Encryption
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Measuring efficiency is difficult. In the last decades, several works have contributed in the quest to successfully determine and compare the efficiency of pairing-based attribute-based encryption (ABE) schemes. However, many of these works are limited:

Attribute-based encryption for circuits [PDF]
Proceedings of the forty-fifth annual ACM symposium on Theory of Computing, 2013 In an attribute-based encryption (ABE) scheme, a ciphertext is associated with an ℓ-bit public index ind and a message m , and a secret key is associated with a Boolean predicate P .
