Challenges

Challenges are fun, and they help us to understand how effective some protection techniques are. On this page, we aim to list challenges related to key hiding in software.

    White-box DES

    A binary executable containing a white-box DES encryption operation with fixed embbeded secret key.

    The challenge was put online in 2007. Two attacks surfaced almost at the same time, independently from each other
    • January 2012, James Muir
    • January 2012, Sysk. Attack has been published in Phrack. See http://phrack.org.
    The challenge has now been accomplished and is hence offline.


At this point, I have no challenges online that I have created myself. But if you are aware of other challenges, don't hesitate to let me know, such that I can include a pointer here.
