Cryptanalysis of Algebraic Eraser
Algebraic Eraser is a public-key key-agreement protocol that’s patented and being pushed by a company for the Internet of Things, primarily because it is efficient on small low-power devices. There’s a new cryptanalytic attack.
This is yet another demonstration of why you should not choose proprietary encryption over public algorithms and protocols. The good stuff is not patented.

This is also yet another demonstration of why IoT is a terrible, terrible idea; even if they had used a better crypto suite, having stuff that isn’t susceptible to attacks because it’s too dumb is always a more robust security choice.
