Secured physically unclonable entities are emerging to play major role in future security systems. Embedding such unclonable entities as integral system component allow to counteract and trace securely a large class of attacks on contemporary networks and systems. Therefore, there is a crying need for low-cost and practically usable and physically clone-resistant or unclonable electronic and/or mechatronic units. Analog Physical Unclonable Functions (PUFs) were introduced two decades ago as

PUFs however, as analog entities, suffer from long-term inconsistency due to aging, operational conditions and other factors. This lead to limiting the practical use of PUFs due to their high-complexity and inherent inconsistency. The digital Secret Unknown Cipher (SUC) concept was introduced a decade ago by a research team at the technical university of Braunschweig as a low-cost and consistent alternative to the conventional analog PUF. SUCs were concepted to be self-created in a single-event, non-repeatable process within electronic devices as clone-resistant modules. The modules represent self-created unknown operational ciphers which may serve as DNA-like biological identities which are hard to duplicate and are securely identifiable. The SUC-concept is an entirely new technology-based security paradigm in the public literature. The new paradigm assumes that the only perfect secrets are those which nobody knows. Such secrets in a practical sense, can only be reached by physical invasive attacks or by exhaustive search requiring infeasible complexity.
