Alif Semiconductor Redefines Edge Device Security with Ensemble Family

Alif Semiconductor has unveiled the Ensemble family, a revolutionary line of Edge AI-enabled secure MCUs and fusion processors. This advanced on-chip security solution introduces a unique security architecture that integrates various cutting-edge technologies, setting a new standard for securing the next wave of deployed Edge devices powered by advanced processing, including Artificial Intelligence and Machine Learning (AI/ML).



Key Innovations of the Ensemble Family:

  1. Integrated Secure Enclave: The Ensemble family features a dedicated isolated subsystem, the Secure Enclave, which manages vital security functions such as secure key management and storage, secure boot with an immutable Root-of-Trust, attestation at run-time using certificates, hardware cryptographic services, secure debugging, read-out protection, secure firmware updates, power management, and complete lifecycle management. This ensures a robust foundation for securing the entire lifecycle of the device.

  2. In-Factory Creation of Unique Device Key Pairs: During manufacturing, the Secure Enclave establishes trust by creating and storing unique device key pairs internally, eliminating the need for external equipment such as a Hardware Security Module (HSM) to inject the keys. This enables every device and customer to establish a chain of trust from the network to the device without introducing complex, risky, or costly third-party dependencies, even after end-products are deployed in the field.

  3. Multi-Core Devices with Secure Firewall Mechanism: The Ensemble family scales from single core to a new class of multi-core devices, combining up to two Cortex-M55 MCU cores, up to two Cortex-A32 microprocessor cores capable of running high-level operating systems, and up to two Ethos-U55 microNPUs for AI/ML acceleration. The Secure Enclave's unique firewall mechanism allows developers to allocate memory and peripherals for each CPU core, ensuring durable separation of resources between multiple processing subsystems and secure and non-secure operations.
