Crypto Core Layer for CC312 on RAFW MCUs. This module implements the CC312 Core library.

Overview

CryptoCell-312 is a comprehensive security solution for low-power, low-area designs. It provides foundational security services for the platform, for example, Secure Boot, key management, and acceleration of cryptographic operations requested by trusted platform components. CryptoCell-312 is aimed at the IoT market, and other areas where there is potential usage of an Arm Cortex-M processor. In most common configurations, the foundational security services of CryptoCell-312 are integrated into the ROM of the platform.

Features

The CC312 Crypto Core module has the following key features:

• Key management
• Secure OTP memory
• Security life-cycle states
• Boot services
• Non-Volatile counters for anti-rollback mechanism.
• Power management
• Device provisioning
• Cryptographic acceleration
• Secure Boot services for the runtime library
• External DMA support

Limitations

Developers should be aware of the following limitations when using the CC312 Core library:

• The Crypto Core library must be combined with the CC312 Crypto library (r_cc312_openable_w) to operate on the target system and RTOS.
• Also, this module does not provide user-accessible APIs.
• Due to ARM CryptoCell licensing & security policies, the source code for this module cannot be opened.
