Google announced Adiantum, a new encryption method devised to protect Android devices without cryptographic acceleration.

Google announced Adiantum,a new encryption method devised to protect Android devices without cryptographic acceleration.

“Adiantum is an innovation in cryptography designed to make storage encryption more efficient for devices without cryptographic acceleration, to ensure thatalldevices can be encrypted.” reads the announcement published by Google.

Since Android version 6.0, user data are protected with Advanced Encryption Standard (AES) encryption, however, the feature is slow on mobile devices using low-end processors that haven’t hardware to support it.

The new encryption form has been created for devices running Android 9 and higher that doesn’t support AES CPU instructions.

For this reason, Google developed Adiantum that supports the ChaCha stream cipher in a length-preserving mode.
ChaCha allows improving security and performance in the absence of...(continued)
