Secure communication
TLS and DTLS client/server capabilities for supported embedded, RTOS, bare-metal and operating-system environments.
Integrate embedded security controls around the device trust model.
Select and integrate security components against the actual threat model, key lifecycle, hardware capabilities, communication paths and update architecture.

Technical scope
Security components within a complete device architecture.
Secure communication, cryptography and firmware controls must be integrated with key provisioning, entropy, hardware isolation, update policy and application-level controls.
Cryptographic services
Configurable symmetric, asymmetric, hash, signature and key-establishment algorithms with platform-dependent acceleration.
Trust integration
Connect keys and operations to supported secure elements, TPMs, HSMs or MCU security hardware where required.
Secure boot
Authenticate firmware before execution using a controlled trust anchor and signing process.
Firmware updates
Design authenticated update, recovery and rollback behaviour appropriate to flash layout and power-failure scenarios.
Validated module options
Use separately scoped validated cryptographic module configurations where the product assurance case requires them.
Implementation workflow
A practical implementation sequence
The implementation should be aligned with the existing engineering process, toolchain and ownership model.
- 01Threat model
- 02Define trust anchors
- 03Select components
- 04Port and configure
- 05Provision keys
- 06Verify update and failure paths
