Authors: Minwoo Lee, Kyungbae Jang, Hyeokdong Kwon, Minjoo Sim, Gyeongju Song, Hwajeong Seo
Abstract:Recently, as quantum computing technology develops, the importance of quantum resistant cryptography technology is increasing. AIMer is a quantum-resistant cryptographic algorithm that was selected as the first candidate in the electronic signature section of the KpqC Contest, and uses symmetric primitive AIM. In this paper, we propose a high-speed implementation technique of symmetric primitive AIM and evaluate the performance of the implementation. The proposed techniques are two methods, a Mer operation optimization technique and a linear layer operation simplification technique, and as a result of performance measurement, it achieved a performance improvement of up to 97.9% compared to the existing reference code. This paper is the first study to optimize the implementation of AIM.
