- Adiantum is a cipher construction for disk encryption, which uses the ChaCha and Advanced Encryption Standard (AES) ciphers, and Poly1305 cryptographic message authentication code (MAC). It was designed in 2018 by Paul Crowley and Eric Biggers at Google specifically for low-powered mobile devices running Android Go. It has been included in the Linux kernel since version 5.0. HPolyC is an earlier variant of Adiantum, which uses a different construction for the Poly1305 hash function. Adiantum is implemented in Android 10 as an alternative cipher for device encryption, particularly on low-end devices lacking hardware-accelerated support for AES. The company stated that Adiantum ran five times faster than AES-256-XTS on ARM Cortex-A7 CPUs. Google had previously exempted devices from mandatory device encryption if their specifications affected system performance if enabled. Due to the introduction of Adiantum, device encryption becomes mandatory on all Android devices beginning on Android 10. (en)
- 铁线蕨（英語：Adiantum）是一种用于磁盘加密的密码结构，它使用ChaCha和高级加密标准（AES）密码以及Poly1305密码訊息鑑別碼（MAC）。 Adiantum由Paul Crowley和Eric Biggers于2018年设计，专门在运行Android Go的低功耗移动设备上使用，在5.0及更新版本的Linux内核中可用。最初谷歌计划使用Speck，但由于Speck与美国国家安全局（NSA）存在太多联系而弃用。 HPolyC是Adiantum的早期版本，它使用与Poly1305散列函数不同的结构。HBSH结构包括散列、分组密码、流密码、散列。 (zh)
