They were always going to need microcode to deal with errata or are you referring to encrypting the microcode rather than just signing it?

- jacquesm 4y agoThe latter. I can see why they did it but if it was used to hide something nefarious Intel is done.
- ta988 4y agoIf they have to hide something, it will not be in the microcode. They always expected it to be broken one day. If it is on the die it will take a massive effort to be found and understood, if ever. And it is actually much easier to hide from the employees as if it was in the microcode, many of them could have extracted the keys and sold them to a foreign power.
