    Has there been any updates on if iMessages on iCloud will be protected by end-to-end encryption (i.e. where Apple doesnt have the keys and wont be able to read even the cloud stored messages)? I found this quote, but it's not very specific:

    I think this feature just kicked on over night. My iPhone now has a ton of old conversations that it must have gotten from other devices... they were not here when I went to bed.

    Same here. It shows a sync was completed at 1AM local time. Side note, I have all of my devices set for 30 day removal but still see messages from a year ago. Wonder which device will control the time messages hang around.

    I wonder if there was an iMessage issue last night. I'm still running iOS10 but I had issues syncing messages between my devices. My iPad was fine but my phone was not getting iMessages last night and this morning. It seems to better now -- I did get a flood of missed conversations about an hour ago on my phone.

    Yeah, that's a fair question to ask. The post is written by someone who hasn't paid attention to WWDC. So it's not a great resource. The iMessages sync feature should have the messages encrypted in transit to Apple and at rest while at Apple.

    However, the iCloud backups are a different thing entirely, and I haven't seen anything new on that front. Since Apple hasn't mentioned it, I'd assume that iCloud backups are as they were in iOS 10.

    The simple answer is yes.

    iCloud data is encrypted for a start.

    iMessage has end to end encryption.

    Why would you think it was any different.

    The failing factor 99.9% of the time is the human one.

    Except it's not encrypted in such a way to prevent access by third parties. Apple holds copies of the keys for the data at rest on their servers.

    They've been getting better, but iCloud Drive, iCloud Photos, and iCloud Backups are definitely not on the same level as iMessages or Keychain is.

    So what if they hold keys. At the end of the day unless your part of some criminal organisation or under investigation for something nasty Apple will protect that data!

    Yes and no, look at it this way... If you can access your data from a vendor's website (i.e. Apple), then they either have the intentional in-built ability or a relatively easy path to access your data with or without your consent.

    It's not just about governments though (let alone yours). If I hold keys to millions of users, that makes me a tempting target. And just one failure to prevent a breach is enough to allow an awful lot of damage. Limiting that damage is a good thing. Nor are all governments of the world my friend. Even assuming the one that has direct power over me is, that's no guarantee any foreign government is.

    But if I'm being honest, the US and UK are surveillance happy enough these days that the surveillance is not nearly as discriminate as it was at the turn of the century. If it was, I wouldn't care too much. But since it is becoming more indiscriminate, I'd much rather make them work for it, thanks.

    aside from the philosophical arguments over the usefulness of end-to-end encryption, does anyone know if Apple implemented it in regards to iMessages sync'ed via iCloud?

    iirc Craig talked about the challenges they faced doing that at the post wwdc Graber talk.
