WhibOx 2019 is a two-day workshop organized by Chris Brzuska (Aalto University) and Pascal Paillier (CryptoExperts) and that will take place in Darmstadt, Germany, on 18th and 19th May 2019, in the same venue as Eurocrypt 2019.
The challenge of white-box cryptography (WBC) is to develop implementation techniques for cryptographic programs to protect their inner keys against an all-powerful adversary that knows the program and can play with it at will. This area of cryptography has long been overlooked and perceived as “impossible to realize” in spite of a strong industrial demand for reliable construction techniques. With the rise of iO on one hand, the emergence of powerful attack techniques such as DCA on the other, and the accelerated deployment of WBC-based applications on smartphones, the field of WBC is currently at a critical point and has never attracted more attention within the crypto community (academia, industry and government agencies). With nearly 200 contestants, 100 AES challenge programs and 900 breaks, the WhibOx competition run in 2017 has shown that this tremendous interest was largely shared within the community, and could also translate into operational work in building or attacking white-box implementations.
Following the WhibOx 2016 workshop and the WhibOx 2017 competition, we are now moving forward with a second edition of the workshop and to a second edition of the competition. WhibOx 2019 will be a unique get-together event for the white-box crypto community in its entirety. With talks on all aspects of the subject (theory, attacks, design techniques) and a hands-on session dedicated to attack tools and demos, the workshop will be an opportunity to advance the field and promote its scientific evolution.
Registration will start at 8:30.
