A Cost-Effective Hardware Architecture for ASCON Against DPA Attacks
Chun-Yen Tsai, Hongchin Lin, Yeong-Kang Lai · 2025
ASCON is a lightweight encryption algorithm that provides efficient security and performance. This algorithm considers noise resistance, high speed, and low resource requirements, making it suitable for various embedded and lightweight application scenarios. However, it still struggles to effectively protect against side-channel attacks such as Differential Power Analysis (DPA). Therefore, this paper proposes an architecture of ASCON against side-channel attacks using the delay and mask techniques with minimal overhead of hardware cost.
