STSAFL010DFSPL01 Authentication & Brand protection secure solution

The STSAFE-L010 system-on-chip is a secure element providing authentication and data management services to a local host.

The primary function of the STSAFE-L010 is to allow the peripheral or consumable to which it is attached to be authenticated by a host for the latter to discriminate between wanted and unwanted peripheral or consumable.

The STSAFE-L010 authentication is performed by generating a digital signature over a challenge sent by the host (traceability data or zone data can be added to the challenge to authenticate it). It uses an Ed25519 signature private key that is unique for each chip and loaded at ST secure personalization center.

On top of authentication, STSAFE-L010 comes with a unique ID and offers a usage monitoring service with decrement-only counters.

A 32 Kbytes nonvolatile memory can be configured in memory zones with different access rights, so that a given zone can always be read but not modified, like manufacturing data, or can freely be modified during the life of the product, to track the way it is used for instance.
