Description

Silicon Labs Secure Engine Manager.

Note

The APIs are thread-safe.

Introduction

The Secure Engine (SE) Manager provides thread-safe APIs for the Secure Engine's mailbox interface. Note that PSA Crypto is the main device independant crypto API and should be used whenever possible, see ls_psa_usage. However, the SE manager APIs can be used directly for performance or space constrained applications.

Modules

Attestation

System and configuration attestation.

Cipher

Symmetric encryption, AEAD and MAC.

Core

Secure Engine Manager Core API.

Entropy

Random number generators.

Hashing

Provides cryptographic hash functions (SHA-1, SHA-224, SHA-256, SHA-384, SHA-512).

Key derivation

API for key derivation and key agreement (ECDH, EC J-PAKE, HKDF, PBKDF2).

Key handling

Secure Engine key handling API.

Signature

Digital Signature Algorithms (ECDSA, EdDSA).

Utilities
