WhatsApp has announced that they will be rolling out end-to-end encryption for its user's backup messages. WhatsApp has already provided end-to-end encryption (E2EE) for its messages between sender and recipient, this time will be applying this to its user's chat history. This was previously saved via cloud-based services, but if the user opts for the E2EE backups, neither WhatsApp nor the backup service provider will be able to access their backup or their backup encryption key. To enable the E2EE backups, WhatsApp developers have created a new system for encryption key storage that works with both iOS and Android. WhatsApp will know that a key exists in the HSM, but it will not know the key itself. • Once the password is verified, the Backup Key Vault will send the encryption key back to the WhatsApp client. • With the key in hand, the WhatsApp client can then decrypt the backups. We've got over a hundred submissions from our recent poll on mobile 3G services.
