Abstract : This paper discusses strategies for the electrical,
integrated implementation of a novel security tool termed SIMPL system,
which was introduced in [1]. SIMPL systems are a public key version of
Physical Unclonable Functions (PUFs). Like a PUF, each SIMPL system S is
physically unique and non-reproducible, and implements an individual
function FS. In opposition to a PUF, every SIMPL system S possesses a
publicly known numerical description D(S), which allows its digital
simulation and prediction. However, any such simulation must work at a
detectably lower speed than the real-time behavior of S. As argued in
[1], SIMPL systems have practicality and security advantages over PUFs,
Certificates of Authenticity (COAs), Physically Obfuscated Keys (POKs),
and also over standard mathematical cryptotechniques. This manuscript
focuses on electrical, integrated realizations of SIMPL systems, and
proposes two potential candidates: SIMPL systems derived from special
SRAM-architectures (so-called "skew designs" of SRAM cells), and
implementations based on analog computing arrays called Cellular
Non-Linear Networks (CNNs).
