A friend shared with me the following link: [Encryption is less secure than we thought](http://www.mit.edu/newsoffice/2013/encryption-is-less-secure-than-we-thought-0814.html)

I'm not a security expert and could understand great part the article, except the section about noise, but what I haven't figured out is the impact of that research in real life.

What does it mean for mortals, in practice?
