Google To Encrypt Cloud Storage Data By Default

jfruh writes "Worries about snooping are now a permanent part of our computing landscape, but Google is attempting to ameliorate those fears by encrypting all data on its Google Cloud Storage service by default. Data is encrypted with 128-bit AES, and you can manage the keys yourself or have Google do it for you. A Google spokesperson said that the company "does not provide encryption keys to any government."" (Also at SlashCloud.)

      Yes, but this prohibits use of Google's many server-side tools for editing documents, spreadsheets, calendar, etc. If confidentiality of your data is to be preserved, that data can never be transferred unencrypted out of machines you control. That prevents the server-side application from checking your spelling, evaluating your spreadsheet calculations, or anything else. The cloud becomes nothing but a distributed filesystem.

      But Google wants to read your data in order to advertise to you. That's why they provide the free service and have implemented all of it server side. They are not dishonest about this, but their denial that they share your data with government authorities seems to ignore the fact that a government can force them secretly to disclose anything.

    Given what we know about the NSA, NSLs, and Lavabits, " [we do] not provide encryption keys to any government" is a worthless statement. With an NSL, Google will turn over everything and won't be able to say anything about it. With an NSL, Google will be required to lie (like claiming data is encrypted when it's not).

      You cannot trust Google or the cloud with your data.

      If you store your data in the cloud, it means that:

      • The 3rd party knows that you have some data stored, and they know its size, and they know how often you modify it or add to it. The observer does not need to have access to your private key to see that.
      • You can never be sure that the data that you deleted was in fact deleted. In most cases, due to existence of tiered backups, it will take a long time to purge your data from an honestly operated system. If the system is ran by a Google-like entity, nothing ever gets deleted.
      • If the observer wishes to decrypt your data, they can always use the $5 wrench, or (if they want to stay undetected) they can send people to duplicate your HDD or to install a keylogger.

      The best way to store your data is on your own HDD, encrypted. The observer still can break into your house, but they would have to do it without any information leading to that. (Such as they wouldn't know that you even have a computer, let alone how often you modify certain files.) Modern terabyte drives (USB 3.0 or eSATA) remove every reason to bother with cloud storage - unless you want an additional bottleneck in form of the Internet link and a bunch of additional vulnerabilities, often for a small extra fee. Most people would be perfectly happy with an encrypted USB Flash disk (IronKey etc.) that they can always carry with them.

    All this buys you is a tiny bit of defense in depth in case someone tracks down the Google server(s) that are storing your data, breaks into the data center, and physically yanks the hard drive out of the machine. Doesn't do anything to prevent a government from getting access by asking politely, and doesn't do anything to address the wide-open front door of someone guessing your account password.

    And the fact the keys are symmetric and held by Google renders the entire exercise entirely worthless. If Google have the key to encrypt/decrypt data then they can just hand it to the NSA or whomever at the same time they hand over the data.

    The proper and correct thing to do is to provide a pluggable API in their client apps that allows an extension running client side to manage the key and encrypt / decrypt the data. And similarly for their cloud APIs for languages like Java.

    Google would have absolutely no idea what the data contains and absolutely no way to retrieve it either. It might mean certain functionality in their apps / services is affected in some ways (e.g. encrypted folders are inaccessible via a browser) but I assume they could spell out the consequences and people motivated to encrypt data would recognize those limitations.
