Module description
The Integrated Management Complex firmware manages functions such as power-on, reset, clock and power control, configuration, and security functions including encryption and decryption, key derivation, key generation, and hashing. The IMC performs these functions as ARM Trusted Execution Environment (TEE) firmware executing on two ARM-A53 processors within the IN762 SoC. The hardware comprises the B227 TRNG, which is a NIST SP800-90 A/B compliant TRNG employed by the IMC module for generating cryptographic keys.
