Implementing a ZK-focused authenticated-encryption scheme
In the last few years, several practitioners have proposed zk-focused cryptographic constructions such as hashing and encryption primitives that operate on binary and prime fields
Practical attacks against attribute-based encryption
This week at Black Hat Europe 2021, Marloes Venema (Radboud University Nijmegen) and me, presented our work on attacking attribute-based encryption implementations: https://www.blackhat.com/eu-21/briefings/schedule/#practical-attacks-against-attribute-based-encryption-25058.
