Tommaso Gagliardoni (Tech Lead Cryptography, Kudelski Security)
Dr. Tommaso Gagliardoni is a mathematician, cryptographer, and privacy advocate. He published influential peer-reviewed papers in the areas of cryptography, quantum computing, security, and privacy, and spoke at many international conferences in these fields. Additionally, he has a background in privacy hacktivism, investigative journalism, and ethical hacking, and being a strong advocate of the FOSS philosophy and digital freedoms. Tommaso obtained a PhD in cryptography at the Technical University of Darmstadt, Germany. He worked at IBM Research before joining Kudelski Security in 2019, where he is currently technical lead for the initiatives in quantum security and advanced cryptography.
Sessions
IMPORTANT INFO: due to personal reason, the speaker won't be able to attend the conference in person. Finally, we will be showing a video of his talk, recorded by the speaker beforehand, and he will then answer any questions participants may have via videoconference.
Shufflecake is a novel, free, open-source data encryption tool that allows the creation of hidden volumes on a storage device in such a way that it is very difficult, even under forensic inspection, to prove the existence of such volumes. This is useful for people whose freedom of expression is threatened by repressive authorities or dangerous criminal organizations, in particular: whistleblowers, investigative journalists, and activists for human rights in oppressive regimes. You can consider Shufflecake a "spiritual successor" of tools such as TrueCrypt and VeraCrypt, but vastly improved: it is fast, supports any filesystem of choice, and can manage multiple layers of nested decoy volumes, so to improve user experience and make deniability of the existence of these partitions really plausible.
Shufflecake is the result of a multi-year research aimed at solving fundamental limitations of plausible deniability tools. It has been peer-reviewed and presented at top IT conferences such as DEF CON Demo Labs and ACM CCS. It is under active development, and the open source community is welcome to contribute. In this talk we will present the history and limitations of other existing solutions, we will show how Shufflecake works and solves such limitations, and we will see why Shufflecake is an indispensable tool in the arsenal of users facing violent or coercive investigation.
