AES-Based Security Coprocessor IC in 0.18-<tex>$muhbox m$</tex>CMOS With Resistance to Differential Power Analysis Side-Channel Attacks

Abstract: Security ICs are vulnerable to side-channel attacks (SCAs) that find the secret key by monitoring the power consumption or other information that is leaked by the switching behavior of digital CMOS gates. This paper describes a side-channel attack resistant coprocessor IC fabricated in 0.18-m CMOS consisting of an Advanced Encryption Standard (AES) based cryptographic engine, a fingerprint-matching engine, template storage, and an interface unit. Two functionally identical coprocessors have been fabricated on … Show more

“…An implementation of a WDDL AES coprocessor, in a 0.18μm 1.8V CMOS technology, was proposed in [9]. It costs a 3 times increase in area, a 3.8 times decrease in throughput and a 3.7 times increase of the power consumption at 50 MHz, compared to its static CMOS counterpart.…”

“…In [12], wave dynamic differential logic circuit with regular routing algorithm is exploited to equalize the current between rising and falling transitions. However, at least double hardware latency, area cost, and energy for unprotected encryption engines are required due to precharging for half cycle, and generating complementary logic outputs from divided single ended modules with equivalent power consumption.…”

“…For example, the Smart Card software is developed on fixed hardware platforms, so the results in that area are software-based solutions. At the same time, many special circuit styles [32,33] have been developed to address PA at the hardware level. Such circuitlevel solutions are treated independently from the software-level solutions.…”
