Hardware Security Features for Secure Embedded Devices
Secure embedded Devices for the mobile, financial and automotive markets require more and more security features to resist today’s field attacks. At the software level, side-channel attacks such as timing attacks, power attacks, electro-magnetic attacks and radio-frequency attacks on embedded devices have been described for a number of years now, and numerous adequate security countermeasures have been published and implemented by most manufacturers. At the hardware level, the story is completely different. Manufacturers have been aware of physical security issues and invasive/side-channel attacks for quite some time, but protecting embedded chips against such attacks requires quite some architectural knowledge and needs to be addressed at the design level. Countermeasures can hardly be added after the fact.
