Usable Security for an IoT OS: Integrating the Zoo of Embedded Crypto Components Below a Common API. (arXiv:2208.09281v1 [cs.CR])

IoT devices differ widely in crypto-supporting hardware, ranging from no
hardware support to powerful accelerators supporting numerous of operations
including protected key storage. An operating system should provide uniform
access to these heterogeneous hardware features, which is a particular
challenge in the resource constrained IoT. Effective security is tied to the
usability of cryptographic interfaces. A thoughtful API design is challenging,
and it is beneficial to re-use such an interface and to share the knowledge of
programming embedded security widely. …
