Alif Semiconductor, supplier of the most power efficient Edge AI-enabled secure MCUs and fusion processors in the market, announced its advanced on-chip security solution. Alif Semiconductor’s unique security architecture brings together a combination of innovative technologies which include an integrated Secure Enclave with its own resources and a highly configurable secure firewall structure, multiple general purpose and neural processing cores with secure communication between them, and in-factory creation of unique device key pairs within every device. Alif leverages all these elements to secure the next wave of deployed Edge devices that are powered by advanced processing including Artificial Intelligence and Machine Learning (AI/ML).
Bullet-Proof Security Baseline in Ensemble Devices
The Secure Enclave, standard in every device of the Ensemble family, is a dedicated isolated subsystem for management of vital security functions like 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.

Going Beyond the Baseline
The Alif Ensemble family scales from single core to a new class of multi-core devices, that combine 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.
For each CPU core, developers may allocate any portion of memory, or any individual peripheral, either shared or separated, using the Secure Enclave because of its unique firewall mechanism. Not only does this grant great flexibility to the developer but also infuses a high level of system security with durable separation of resources between multiple processing subsystems as well as secure and non-secure operations. This extends security well beyond the capabilities of traditional Arm TrustZone that is optimized for single-core operation.
