Google makes disk encryption in Android Q mandatory for all smartphone manufacturers. The mobile operating system also gets some other new security features, such as a sandbox for software codecs and support for TLS 1.3.
Google describes the new security features in a blog post. The company uses the new Adiantum encryption method to enable disk encryption in all devices. Adiantum was presented in February. Although disk encryption is already enabled in most modern Android devices, manufacturers of low-end smartphones sometimes opt to disable encryption. Adamantium is intended to enable encryption on such CPUs without a reduction in performance.
Android Q also receives support for TLS 1.3, the successor to TLS 1.2. Stronger encryption is used in 1.3, and it would be up to forty percent faster than the previous version. The company has also made an update to the BiometricPrompt API that is used for biometric authentication within the operating system and apps. The update gives developers more options to expand the method.
Finally, Android Q receives support for Electronic ID. This allows a telephone to be used as an identity or driver’s license. According to Google, it will take a while before Android can actually use that function because it cooperates with standardization institute ISO.
