Windows The story about how secure boot for Windows 8, part of UEFI, will hinder the use of non-signed binaries and operating systems, like Linux, has registered at Redmond as well. The company posted about it on the Building Windows 8 blog - but didn't take any of the worries away. In fact, Red Hat's Matthew Garrett, who originally broke this story, has some more information - worst of which is that Red Hat has received confirmation from hardware vendors that some of them will not allow you to disable secure boot.

RE[5]: RSA key example.

Member since:

An idea hash function means that the only way to find a collision is to brute force various inputs until we generate a collision.

This is the part which I don't understand. I don't get how it is possible to create a hash function and publicly distribute it, in a way that mathematicians are not able to find collisions just by studying the form of the hash function itself.

This is if we stick to classical computing, quantum computing introduces yet a whole new dimension to the problem. It's too bad quantum computing was not offered at my university, since I don't know that much about it.

Well, I have a course on it later this school year (jan-feb 2012), so I can send you lecture notes if you want. It's targeted towards physicists, though, so maybe you would experience a feeling of unbalanced complexity, the mathematical part looking over-explained while the physical part would look under-explained.
