The resulting mechanism planned for getting the keys automatically distributed is to utilize Microsoft key signing and registry services. This obviates the need for every customer to have to round up a collection of keys for multiple operating systems and device drivers. Microsoft will provide keys for Windows and Red Hat will provide keys for Red Hat Enterprise Linux and Fedora. Similarly other distributions can participate at a nominal cost of $99 USD – allowing them to register their own keys for distribution to system firmware vendors.
