Can We Tolerate Small Side-Channel Leakages: The Role of Registers in Glitch-Stopping Circuits

본문 미리보기

Research on cryptographic algorithms implemented in hardware and protected against side-channel attacks has advanced rapidly in recent years. Generalized masking schemes, such as Threshold Implementations (TI) and Domain-Oriented Masking (DOM), currently provide a solid theoretical security foundation. Security models, including the probing model and its various extensions, enable formal verification of these guarantees. In addition, established guidelines for designing securely composable gadge
