Adiantum Is Taking Shape As Google's Speck Replacement For Low-End Device Encryption

Earlier this year when Google added Speck-based file-system encryption support to the Linux kernel they intended it to be used by low-end Android phones/smartwatches with older ARM processors lacking the dedicated ARM cryptography extensions. Speck is fast enough to provide disk encryption on the low-end hardware, but ultimately they decided against Speck due to public outcry with the algorithm potentially being compromised by the US NSA. Instead Google engineers decided to pursue HPolyC as their new means of encryption on low-end hardware while now that has evolved into a new technology dubbed Adiantum...
