Arm is soliciting feedback on a proposed interface to random generator drivers for a PSA cryptography library or service. In a nutshell, this is the interface between portable code that implements cryptographic operations and keystore functionality, and drivers for hardware that provide an entropy source, acceleration of a random generation algorithm, or both.
The current specification draft is attached to this email in markdown and HTML formats.
Comments are welcome through the following venues: * Public email to the psa-crypto list at TrustedFirmware. * Private email to email@example.com. These emails will only be shared inside Arm. We may use your feedback to influence the design of PSA Crypto, but your identity and the specifics will be kept confidential.
We would appreciate it if any major issues were raised before 31 January 2021.
