Energy-Efficient Side-Channel Attack Countermeasure With Awareness and Hybrid Configuration Based on It.

Energy-efficient countermeasures to side-channel attacks are required for Internet of Things hardware. This paper proposes a special hiding technique for the substitution operation in block ciphers, which equalizes the power consumption of a circuit by appropriate feedforward compensation and is called power-aware hiding (PAH). A hybrid application configuration, in which PAH is applied to the S-b...
