Hardware-Level Mitigation of Micro-Architectural Leakages in Embedded Processors

본문 미리보기

Cryptographic software, with its inherent flexibility and adaptability, has become essential for meeting today’s rapidly evolving security requirements, despite offering lower performance than dedicated hardware accelerators. However, Side-Channel Analysis (SCA) complicates its secure execution on physical hardware, making robust protection a central challenge. While the masking countermeasure offers provable security guarantees in theory, its effectiveness is often undermined by the processor’s
