Google Drops Plan for Speck Encryption in Android

It's sad that the original story got so much attention, yet this change of direction gets so little.

TLDR; the encryption wasn't performant enough, so dropped encryption all together. Makes sense...

What? No. That's not the TL;DR at all.

AES in XTS mode wasn't performant enough. Speck in XTS mode was a candidate, but it had a very dubious background.

So, instead they developed construct based on existing trusted primitives that is faster than both AES-XTS and Speck-XTS on the target hardware.
