Applications
Embedded security applications from device boot to secure connectivity
Embedded TLS and DTLS
Secure client, server and device communication across constrained MCUs, RTOS systems and embedded Linux. Libraries can be configured for limited memory, hardware acceleration, specific protocol profiles and the target operating environment.
Secure boot and firmware update
Authenticate firmware, protect update workflows and prevent unauthorised code execution. Signed images, rollback protection and trusted key handling establish a controlled chain from power-on to application execution.
Automotive and industrial security
Cryptographic components for connected controllers, gateways, ECUs and industrial devices. Portable cryptographic components can be integrated into gateways, controllers and ECUs without a general-purpose desktop security stack.
IoT and cloud connectivity
Secure MQTT, SSH and TLS communication between devices, gateways and cloud services. Device communication can combine TLS, MQTT and SSH for secure onboarding, telemetry and remote maintenance.
