How to detect hardware tampering and protect chips against attacks by quantum computers
This piece discusses the vulnerability of hardware chips to physical tampering and the emerging threat posed by quantum computing. It emphasizes that unlike software, hardware security flaws are often permanent and difficult to detect once integrated into critical infrastructure.
Why it matters
Securing the physical hardware layer is essential for national security and the stability of global digital infrastructure against sophisticated cyber threats.

Add to Preferred Sources Barely larger than a fingernail: This chip is like a tiny computer. Sixty-four metal pins protrude from the black casing. Some of these contacts are used for power, for example, but the vast majority are used for the input and output of commands and signals. Credit: Judith Büthe for MPG Software can be updated. Hardware cannot. Manipulation deep within a chip would be almost impossible to detect—and could threaten entire infrastructures. At the same time, it is now more important than ever that we prepare hardware for impending attacks using quantum computers.
