COPPER - Improving cost-efficiency of PUF-based IPS diversification
Our fifth project COPPER investigates the effects of PUF-based diversification on the surrounding software ecosystem. The need to gain understanding about the process is illustrated by the lack of existing frameworks to understand the impact of diversification on a sufficiently high level.
If an adversary expects a diversification of a program with a probability of 20 %, this expectancy may give him an edge in attacking the system. We propose, therefore, to introduce slight variations guaranteeing that manufacturers will not fall into this complacency trap.
A further goal is to embed PUF-based IPS diversification into various production systems of manufacturers and study their impact on software production costs. In addition, we will focus on reducing overall costs of the enrollment of challenge-response pairs (CRPs) in PUF.
