Smaller, smarter and faster edge devices in the Internet of things era
demands secure data analysis and transmission under resource constraints of
hardware architecture. Lightweight cryptography on edge hardware is an emerging
topic that is essential to ensure data security in near-sensor computing
systems such as mobiles, drones, smart cameras, and wearables. In this article,
the current state of memristive cryptography is placed in the context of
lightweight hardware cryptography. The paper provides a brief overview of the
traditional hardware lightweight cryptography and cryptanalysis approaches. The
contrast for memristive cryptography with respect to traditional approaches is
evident through this article, and need to develop a more concrete approach to
developing memristive cryptanalysis to test memristive cryptographic approaches
is highlighted.Comment: European Physical Journal: Special Topics, Special Issue on
