I recently presented work on the analysis of a file encryption solution that claimed to implement “AES-1024 military grade encryption“. Spoiler alert: I did not
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
Hello Web3/blockchain world, great job. You got people to take you seriously, trusting your projects and investing their money. You’ve sold people on your innovations,
Summary An anonymous attacker used a verification problem in the Wormhole program and 80000 wETH were pulled out of the Wormhole contract. The problem was
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.
