Existing cloud storage protection solutions use passwords to derive encryption keys. This allows easy access to encrypted storage from multiple devices. However, this approach is vulnerable to brute force attacks and requires user engagement. We want to provide a solution which uses client-side encryption with strong keys (possibly protected by on-device trusted hardware) without significant reduction in the user experience. The solution is also available on different types of devices (Mobiles, Desktop).
