Approximate computing is a promising approach for error-tolerant applications running on the Internet of Things (IoT) edge devices to reduce power consumption. However, approximate computation is susceptible to side-channel attacks, such as attacks based on Differential Power Analysis (DPA). Energy efficiency could be further enhanced by applying adiabatic logic in approximate edge computing while increasing its protection against the side-channel attacks. As a case study, we are presenting two approximate adders based on adiabatic logic to illustrate the benefits of approximate computation combined with adiabatic logic. The proposed approximate adders leverage the dual-rail property of adiabatic logic to minimize the overall size and further decrease energy consumption.
