Secure Design Considerations for Embedded Systems

Abstract

A guide is presented for embedded system designers that details secure design considerations for modern embedded systems. The guide focuses on adapting traditional software design practices to include adapted methodologies for defining, evaluating and producing effective solutions to security problems. Adapted threat modeling and analysis techniques are provided as a framework upon which to further critique, analyze and implement other security techniques as solutions to security problems. Simple implementations and analysis are provided for three encryption algorithms as examples. The encryption algorithms are demonstrated as only one of many solutions available to designers for secure development.
