Google Standardizing Secure Element Interfaces for Digital Keys, IDs, and Wallets
Google recently announced the formation of the Android Ready SE Alliance, a collaboration between Google and the makers of "secure element" chips for phones and similar devices. The new initiative will enable all Android phone makers to more easily implement hardware security features that match the functionality and security of Pixel phones (which use Google's Titan M secure element chip). A secure element is discrete, tamper-resistant hardware that protects the integrity a user's data, keys, wallet, etc. The Android Ready SE Alliance has specific requirements to ensure that implementations are secure. The Alliance is also releasing specific software called SE Applets, which run on the secure element chips and implement specific features "in conjunction with corresponding Android feature releases". The first Applet is StrongBox, which simply stores and handles cryptographic keys. The next two Applets will be for digital IDs (including mobile driver's licenses) and digital car keys. Phone makers can choose secure element chips from any of the five participating hardware vendors: Giesecke+Devrient, Kigen, NXP, STMicroelectronics, and Thales.
