Embedded devices are increasingly involved in applications that store, access, and manipulate sensitive information. This creates a need for protecting such devices from security threats. However, resource-constrained nature of these devices does not allow engineers to apply conventional security mechanisms in a straight forward manner. For instance, Ravi et al. identify resource-oriented gaps which are related to incorporating security solutions in embedded devices; in particular, the so-called battery and processing power gaps. To address these issues the authors propose to shift security considerations to earlier development stages, and support the embedded engineer in incorporating security solutions.
