What is zero-access encryption and why is it important for security? | Proton
Most of us would not give our private, personal information to strangers and then trust them not to leak it. But that’s essentially what we do every time we store chat histories, email, documents, and pictures on the cloud. When you save a document to Google Drive, a photo album to iCloud, or an intimate conversation to Facebook Messenger, you are trusting that this information will not be breached or misused.
There are ways, however, to encrypt your data so that only you can access it, and zero-access encryption is one of these methods. Zero-access encryption is a way of protecting data at rest — that is, while the information is sitting in storage on the cloud. With this type of encryption, even if hackers were to breach the provider’s servers and steal your files, they would not be able to decrypt the data. Zero-access encryption ensures that only you, the data owner, have the technical ability to read your data.
How does zero-access encryption work?
Zero-access encryption is just what it sounds like: a type of encryption(yeni pencere) for data at rest that renders digital files inaccessible to the service provider. The files can only be decrypted using the user’s private encryption key. Because the server does not have access to the user’s private encryption key, once the files are encrypted with the user’s public encryption key they are no longer accessible to the server or the server’s owner. When the data owner wants to view their data, they request the encrypted files from the server and decrypt them locally on their device, not on the server.
How is zero-access encryption different from end-to-end encryption?
At Proton Mail, we use both zero-access encryption and end-to-end encryption(yeni pencere) to protect your data. To understand the difference, consider two scenarios:
1. Someone using a Gmail account sends an email to a Proton Mail account. When it arrives at Proton Mail, our servers can read that email because Gmail does not support end-to-end encryption. However, after receiving the email, we encrypt it immediately using the Proton Mail account owner’s public encryption key. Afterwards, we are no longer able to decrypt the message. In fact, the encrypted email can now only be decrypted by the Proton Mail account owner.
2. Someone using a Proton Mail account sends an email to another Proton Mail email address. The email is encrypted on the sender’s device using the public encryption key of the recipient before being transferred to the Proton Mail server and to the recipient. Thus, the message is already encrypted before it reaches our server, and only the sender and the recipient have the ability to decrypt the email. This is end-to-end encryption.
As you can see from these examples, end-to-end encryption is the stronger of these two types of encryption because Proton Mail never sees the unencrypted message. Zero-access encryption does prevent the messages in your mailbox from being shared with third parties or leaked in the event of a data breach, but those messages are accessible to Proton Mail servers for a split second before the message is encrypted. For these reasons, we generally recommend that for highly sensitive conversations, both parties use Proton Mail to take advantage of the stronger end-to-end encryption.
Zero-access encryption solves big security problems
Most companies do not implement zero-access encryption either because they sell your private information to advertisers (Google, Facebook, etc.) or because the technical challenges of implementing it are too great.
Instead, they might use regular encryption where they retain control over the encryption keys. This is like storing the key to the lock with the lock itself and creates many vulnerabilities. For example, if servers are ever hacked, your private conversations can be leaked (like in the Yahoo! breach(yeni pencere) of all 3 billion of its accounts).
Furthermore, this approach also leaves data open for misuse, either by rogue employees or unscrupulous third parties, such as in the Cambridge Analytica/Facebook scandal(yeni pencere). This data can also be made accessible to government surveillance agencies or sold outright to advertisers.
We drastically reduce these security and privacy vulnerabilities by using zero-access encryption to ensure that we ourselves do not have access to your data. That way, even if somehow Proton Mail servers are breached, the contents of users’ private emails will still be encrypted. Both zero-access encryption and end-to-end encryption are essential to ensure good protection against data breaches and privacy violations in the digital age, and for this reason, they are highly recommended by experts(yeni pencere) and important for complying with data protection laws such as the GDPR law.
