258: Security Is Another Dimension
Axel Poschmann, head of the hardware security lab at DarkMatter, discusses embedded security as a trade-off against usability and cost, emphasizing that perfect security is impossible. He outlines a practical workflow for securing IoT devices, including threat modeling, using constant-time crypto libraries, and leveraging low-cost third-party testing or university collaborations when budgets are tight. Poschmann also explains how hardware countermeasures like fuses and physical obfuscation raise the barrier for attackers, referencing standards like Common Criteria and resources such as Christof Paar’s cryptography lectures and ENISA’s guidelines.
