Is this technically equivalent to Google’s proposal? Apple say that their version was developed in collaboration with Google, so it would be surprising for Google to go and deploy a second version of the same thing, were it not for the fact that Google always has two competing versions of everything.
And I guess the main reason people are more concerned about Google’s version is that they are so dominant in the browser market.
The details are a bit different. PATs use HTTP headers during a request while WEI is a JS browser API. But otherwise the general structure and end result are the same. A website requests an integrity check, an attester checks your device, and if the attester doesn’t like your device then you’re SOL.
