如果不使用内嵌加密硬件,建议fileencryption=aes-256-xts 如果使用内嵌加密硬件,建议fileencryption=aes-256-xts:aes-256-cts:inlinecrypt_optimized(或等效的fileencryption=::inlinecrypt_optimized) 如果没有使用任何形式加速的AES,建议fileencryption=adiantum Android 10及以下版本,用 fileencryption=ice 来指定文件内容...
文件加密 (FBE:File-Based Encryption) FBE 允许使用不同的密钥加密不同的文件,这些密钥可以独立解锁。FBE 引入了一种称为 Direct Boot 的新引导方法。使用直接启动,加密设备可以直接启动到锁定屏幕。在启用 FBE 的设备上,设备的每个用户都有两个可供应用程序使用的存储位置:凭据加密 (CE) 存储,这是默认存储位置...

That was the reason of researchers want to add cryptography which the combination between Advance Encryption System (AES) dan Ron Rivest, Adi Shamir dan Len Adleman (RSA). The result of the second method above could do cryptography data on mobile. With different encryption time where the file ...
Now, with file-based encryption (or full-disk encryption), the user's filesystem data (including Keystore keys) is encrypted using the user's screen lock method and that is handled at a different layer than Keystore - so there's no benefit to encrypting Keystore keys any longer. Contribu...
