Attacking Pairing-Free Attribute-Based Encryption Schemes [PDF]
IEEE Access, 2020 Combining several results that have been published in the last years, it is known that it is impossible to design simple and secure attribute-based encryption schemes that work in (classical) settings like the RSA or the pairing-free discrete logarithm ...

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:

Multiauthority Attribute-Based Encryption With Dynamic Membership From Lattices
IEEE Access, 2022 Attribute-based encryption is useful for one-to-many encrypted message sending. However, most attribute-based encryption schemes authorize and issue attributes to users by a single authority.

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 .
