More on Kish's Encryption Scheme
Back in 2005, I wrote about Laszlo Kish’s encryption scheme, which promises the security of quantum encryption using thermal noise. I found, and continue to find, the research fascinating—although I don’t have the electrical engineering expertise to know whether or not it’s secure.
There have been developments. Kish has a new paper that not only describes a physical demonstration of the scheme, but also addresses many of the criticisms of his earlier work. And Feng Hao has a new paper that claims the scheme is totally insecure.
Again, I don’t have the EE background to know who’s right. But this is exactly the sort of back-and-forth I want to see.
