Secure Context Switching of Masked Software Implementations

ePrint Report: Secure Context Switching of Masked Software Implementations

Barbara Gigerl, Robert Primas, Stefan Mangard

Cryptographic software running on embedded devices requires protection against physical side-channel attacks such as power analysis. Masking is a widely deployed countermeasure against these attacksand is directly implemented on algorithmic level. Many works study the security of masked cryptographic software on CPUs, pointing out potential problems on algorithmic/microarchitecture-level, as well as corresponding solutions, and even show masked software can be implemented efficiently and with strong …
