I came across the Underhanded Crypto Contest recently. Anyone on here interested in forming a team and putting together a submission?
The idea is to design a cryptosystem or modify an existing one, in such a way that the code looks fine but has a subtle flaw that should escape expert detection.
The submission deadline is 02 December 2014.
If we get a few people interested (just leave me a comment here or in chat), I'll create a chat-room and invite those who respond. We can use that to discuss ideas and plan our submission.
Any level of participation would be great. Even if all you can do is pop in on chat and critique our ideas, that would be very welcome. We will need people who can help implement the idea though too.
I see this as a great way to promote the site and our community.
