文摘

Side-channel analysis (SCA) attacks pose a serious threat to embedded systems. So far, the research on masking as a countermeasure against SCA focuses merely on cryptographic algorithms, and has either been implemented for particular hardware or software implementations. However, the drawbacks of protecting specific implementations are the lack of flexibility in terms of used algorithms, the impossibility to update protected hardware implementations, and long development cycles for protecting new algorithms. Furthermore, cryptographic algorithms are usually just one part of an embedded system that operates on informational assets. Protecting only this part of a system is thus not sufficient for most security critical embedded applications.
