EMBOSOM - Emigrating Embedded Software Security into Modern Emerging Hardware Paradigms

点击翻译按钮获取中文摘要

In order to protect software against the exploitation of vulnerabilities, it is paramount to have sufficient protection mechanisms in place. This is especially important in the embedded domain, where such vulnerabilities can cause harm in the real world. However, prior work has shown that common software protection mechanisms are not available in this domain. While state-of-the-art protection mechanisms are mainly implemented in software, an emerging research direction is implementing such techniques directly in the hardware. Unfortunately, existing work in this domain targets non-constrained conventional devices which have a different threat model. Furthermore, existing work on such hardware protection mechanisms imposes a significant impact on essential characteristics of the embedded domain such as chip size, performance, and production costs. We want to develop a novel hardware-based security mechanism which is specifically tailored to the threat model of the embedded domain and leverages emerging technologies (e.g. memristor-based in-memory computing) to reduce the impact on performance, power consumption, and chip size. The proposal belongs to research area 3 (Secure Composition and Integration) and the interdisciplinary group on secure processing via hardware-supported data separation and isolation (IG2) of the call's matrix.
