Honestly this article is not really saying much and seems like the person who wrote it probably doesn't have a good understanding of the subject. It isn't like a wireless car ignition system transmits a password, they use zero knowledge proof of knowledge and allow for a total interception. The most I can get out of this article is that some new understanding of entropy has been arrived at, and it probably means that non-randomly generated passwords are easier to crack than previously thought, and perhaps that some cryptographic systems are also easier to directly break than was previously thought. I would need to read the paper and not this article to see what is up though, because the article doesn't really do a very good job of giving me the raw information.
