Adiantum is a new form of encryption that we built specifically to run on phones and smart devices that don’t have the specialized hardware to use current methods to encrypt locally stored data efficiently. Adiantum is designed to run efficiently without that specialized hardware. This will make the next generation of devices more secure than their predecessors, and allow the next billion people coming online for the first time to do so safely. Adiantum will help secure our connected world by allowing everything from smart watches to internet-connected medical devices to encrypt sensitive data. (For more details about the ins and outs of Adiantum, check out the security blog.)
Encryption should be available on every single Android phone, not just the high-end, expensive models only the lucky few in the world can afford. Good move.
