A new technical paper titled “Hardware trojans in superconducting electronic circuits” was published by researchers at University of Rochester.
The paper explores Hardware Trojans tailored for superconducting electronic (SCE) circuits, including magnetically-coupled data transmission and pulse-interleaved Trojans embedded in SFQ full adder and frequency divider circuits, respectively.
These Trojans exploit the frequency-sensitive nature of SCE circuits, remaining hidden during low-frequency testing and becoming active at higher frequencies, emphasizing the need for enhanced security measures.
The study highlights the importance of comprehensive security measures considering various operating frequencies to safeguard classical superconducting systems and future quantum technologies.
