PUF for the Commons: Enhancing Embedded Security on the OS Level. (arXiv:2301.07048v2 [cs.CR] UPDATED)

Security is essential for the Internet of Things (IoT). Cryptographic
operations for authentication and encryption commonly rely on random input of
high entropy and secure, tamper-resistant identities, which are difficult to
obtain on constrained embedded devices. In this paper, we design and analyze a
generic integration of physically unclonable functions (PUFs) into the IoT
operating system RIOT that supports about 250 platforms. Our approach leverages
uninitialized SRAM to act as the digital fingerprint for heterogeneous devices.
We ground our design …
