Computers and cryptographic hardware eventually are no Turing machines living in a Platonic world, but real, physical objects that can be touched and accessed, and which consume power, dissipate radiation, or are susceptible to faults and invasive manipulation. This simple observation has had a massive impact both for codemakers and codebreakers over the last decades.
On the side of codebreakers, various attacks have been developed that specifically target the physical nature of electronic hardware; they include invasive and semi-invasive read-out techniques, fault injection, photonic emission analysis, power or other side channels, and also hardware Trojans, only naming a few. Complementary to that, physical phenomena like quantum effects or optical interference can allow faster computations than classical Turing machines for certain cryptographically relevant problems. This enables novel computational attack vectors based on physics, too.
On the other hand, physics provides equally powerful tools for codemakers. To start with a particularly popular example, quantum physics allows exchanging a secret key that is provably unknown to eavesdroppers, and that remains so forever – a security level impossible to realize by traditional digital means, such as the Diffie-Hellman protocol. Secondly, various electrical, optical, or quantum mechanisms have been suggested to meet of the central needs in cryptographic protocols, namely the generation of true, secure randomness for any involved parties. Finally, the phenomena of physical randomness and unclonable, small-scale disorder have been exploited by so-called physical unclonable functions, a tool that has strongly influences our thinking on hardware security over the last two decades.

Submitted papers must include new significant research-based technical contributions in the scope of the journal. Purely theoretical, technological, or lacking methodological-and-generality papers are not suitable. The submissions must include clear evaluations of the proposed solutions (based on simulation and/or implementations results) and comparisons to state-of-the-art solutions. Papers under review elsewhere are not acceptable for submission. Extended versions of published conference papers (to be included as part of the submission together with a summary of differences) are welcome, but there must be at least 40% of new impacting technical/scientific material in the submitted journal version and there should be less than 50% verbatim similarity level as reported by a tool (such as CrossRef). As per TETC policies, only full-length papers (10-16 pages with technical material, double column – papers beyond 12 pages will be subject to MOPC, as per CS policies) can be submitted to special sections. The bibliography should not exceed 45 items, and each author’s bio should not exceed 150 words.
