STMicroelectronics STSAFE-L010 Authentication System-on-Chip
STMicroelectronics STSAFE-L010 Authentication System-on-Chip (SoC) is a secure element providing authentication and data management services to a local host. The main role of the STMicroelectronics STSAFE-L010 is to enable the host system to verify and differentiate between authorized and unauthorized peripherals or consumables. Authentication is achieved by generating a digital signature in response to a challenge sent by the host. This challenge can include traceability or zone-specific data for enhanced verification. The signature is created using a unique Ed25519 private key embedded in each chip during secure personalization at ST.
Beyond authentication, the STSAFE-L010 includes a unique identifier and supports usage monitoring through decrement-only counters. The SoC also features 32KB of nonvolatile memory, which can be divided into zones with configurable access rights. For example, some zones may be read-only (ideal for storing manufacturing data), while others can be freely updated throughout the product’s lifecycle to track usage or other dynamic data.
