Mifare

[James A. Donald]

http://www.youtube.com/watch?v=NW3RGbQTLhE shows the researchers
breaking Mifare.

And in the comments, we see posts (I presume from mifare people) 
complaining that what is happening cannot possibly be happening.

Everyone on this list knows the correct way to do what Mifare does wrong.

So, since we all know how to do it right, why did Mifare come up with 
their own super secret snake oil algorithm that no one ever reviewed?

More generaly, why is encryption generally implemented in such a damned 
stupid manner?

Now everyone is going to say it should have been put out for review, and 
of course it should have been, and had they done so they would have 
avoided these particular mistakes, but DNSSEC and WPA was reviewed to 
hell and back, and the result was still no damned good.
