Snake Oil Crypto Competition (cr.yp.to)

I was disappointed to realize the snake-oil competition is a parody, because a properly-implemented version of it could teach valuable lessons to non-technical consumers.

Many products make outrageous claims about their security. Try browsing the aisles of Best Buy or any major department store. From smart-home sensors to security-cameras to anti-virus software, the shelves are stocked full with snake-oil security products advertising themselves as legitimate. These are the products that big retailers and OEM partners are marketing to the public as "secure," with much lower standards for security than any expert would assert.

To prove this to the public, what better way than a competition for benevolent security researchers to create a wolf-in-sheeps-clothing? The competition is to produce most shiny, marketable product design that looks like a "security" product, but does something far more sinister than protect its users.

Product ideas: "Anonymous router" that actually logs all traffic and sends it to a printer in the local police office; "Smart Home Hub" that performs active exploitation attacks against connected devices; "Smart TV" that actually films its users and live streams their living room to a website.

(Bonus points if they credit real products!)


You must be looking for the Underhanded Crypto Contest: The Underhanded Crypto Contest is a competition to write or modify crypto code that appears to be secure, but actually does something evil. See https://underhandedcrypto.com/


related: the Underhanded C Contest ( http://www.underhanded-c.org/ )

Apparently this year's contest just opened.


"Smart TV" that actually films its users and live streams their living room to a website.

That's been done, 2 years ago:

I clicked on one of the submissions and the paper is in Comic Sans: http://snakeoil.cr.yp.to/submissions/Lolcipher%20Submission....

This is hilarious.


I'm glad I took the time to read this


I assume this is something put up by Dan Bernstein, since that's his domain.

Please, can someone explain what this is about? E.g. Dan mentions the inventors of Rijndael, which is AES. What is his complaint about it?


The major complaint against AES is that it is very difficult to implement in a data-independent way without hardware support. Bernstein has done some research on this (http://cr.yp.to/antiforgery/cachetiming-20050414.pdf), and a major theme of his research has been designing systems that are friendly to implementers.

I have no idea if that is what this specific dig ("they already master the art of snake oil") pertains to.


I'm not qualified to answer that question, but I was curious too, did some googling and found another resource. This is still not very satisfying, but there is a little more information on the Reddit thread about this competition:

>Retraction of the idea to change parameters.

Speaking of Keccak their landing page is full of snake-oily marketing such as "rock-solid security strength level" and "heavier SHAKE512" or "extremely high 256 bits" like they are trying to sell me a battle armor video game addon. I realize there is misinformation floating around ever since the questionable SHA3 competition but bolding arbitrary words and injecting "rock-solid" into your criticism debunking isn't helping. http://keccak.noekeon.org/


"The questionable SHA3 competition"?


> "Potential extra features (worth extra points):"

> "+ Protection against front-channel attacks."

I think I just hurt myself laughing.



Yesterday I started writing a paper for Snake Oil Crypto Competition and today I sent it them. I hope they will accept it!


I wonder what the general crypto communities views on Kenny Patterson, Orr Dunkelman, Stefan Lucks or Tanja Lange are.


The only name on that list that I know off the top of my head is Tanja Lange, and she has earned a lot of respect for her work.

https://www.youtube.com/watch?v=l6jTFxQaUJA - Her and the author of this parody at 31C3 last year, teaching ECC.


That list of names is a decent slice of "the general crypto community".


I am not really part of the "crypto community", but I know that Tanja Lange and Orr Dunkelman are both held in high regard (am not familiar with the other two names).


Kenny Paterson is the new co-chair of IETF CFRG and a professor at RHUL. Best known recently for his work breaking RC4.

Lucks is a well known research cryptanalyst and one of the co-inventors of the Skein SHA3 finalist.


rot26 ftw!
