That's a much more defensible claim---one I have no issue with---but it was easy to misread the post and believe it was claiming something more general.

- cperciva 9y agoThanks! It's getting late here (3 AM) so this might not be the best wording, but would it help if I added a note after the third paragraph along the lines of "Note that there have been previous side channel attacks which depended on how microarchitectural features (usually caches) affected code execution; but my work was the first to demonstrate information leaking from a program into the microarchitectural state and then being extracted from there." ? (Feel free to suggest other wording too -- as I said, it's getting late here and my word-putting-together skills are currently subpar.)
- pbsd 9y agoThat seems fine on its own, but it somewhat undermines the paragraph with "but they have all followed the same basic mechanism", seeing as these earlier attacks relying on caches etc did not follow this mechanism. Changing "all" to "most" or "many" would probably suffice.
- cperciva 9y agoAh, that should have said over the following years.
