Adding extra hardware security for secure embedded devices

摘要

Dr. Helena Handschuh and Dr. Elena Trichina explore the types of attack that hardware can be subjected to and how manufacturers continually add hardware-based security features to their products. Different flavours of side-channel attacks such as timing attacks, power attacks, electromagnetic attacks and radio-frequency attacks on cryptographic algorithms have been studied on embedded software for over a decade; the idea behind these attacks is that the measurements (computation time, power consumption, electro-magnetic radiation) are data-dependent and statistical analysis of the collected curves reveals the secret key.
