Overview

This reference manual provides a detailed software description of the API for the Hardware Security Module (HSM) solutions within the EdgeLock Enclave (ELE) platform. It covers NXP i.MX 8ULP, i.MX 91, i.MX 93, i.MX 95, and i.MX 943 processors. The document explains core concepts including session initialization, service flow management, and key store operations for symmetric and private keys. It details cryptographic operations such as hashing, signature generation and verification, ciphering, and message authentication codes (MAC). Additionally, it describes the Cyber-Resilient Recovery Module (CRRM) for attack detection and the management of key groups within local memory and external non-volatile memory (NVM).

Use Cases

Developing secure Linux-based applications on i.MX 8ULP and i.MX 9 series processors
Implementing hardware-accelerated cryptographic services including signatures and encryption
Managing secure key storage and lifecycle within the EdgeLock Enclave
Configuring automated cyber-resilient recovery for edge computing devices
