Advanced Topic 48 of 50 Mobile, Embedded & IoT

Embedded Security

Securing devices with secure boot and key storage.

How it works

Embedded security protects devices from attack throughout their life. Measures include a hardware root of trust, secure boot that verifies each firmware stage's signature, encrypted and signed firmware updates, storing keys in secure elements or trusted execution environments, disabling or locking debug interfaces such as JTAG in production, memory protection units, least-privilege design, unique per-device credentials, encrypted communications with TLS or DTLS and secure provisioning. Threats include physical access, side-channel and fault injection attacks, firmware extraction and network exploits.

Where it is used

Medical devices, vehicles, industrial controllers, smart locks and consumer IoT products are increasingly regulated, with standards such as IEC 62443 and the EU Cyber Resilience Act.

Common pitfall

Default or hard-coded passwords and unpatched firmware have led to large botnets. Security added late is costly. Devices often live for decades, so support and updates must be planned. Constrained hardware limits cryptography choices. Threat model early, use proven libraries, enable secure boot, avoid shared keys and plan vulnerability handling.

Where it fits in the course

Embedded Security is topic 48 of 50 in Mobile, Embedded & IoT, rated Advanced. It follows Wearable Computing. The next topic is Real-Time Constraints and Scheduling.
