3 Main Features

The CC33xx companion IC offers a wide range of built-in security features. These security features can enable and assist designers with addressing a variety of security requirements and reducing the security risk with the intended application.

Table 3-1 lists high-level descriptions of the main security features.

Table 3-1 Main Security Features
Feature Description
Personal and Enterprise Wi-Fi security 802.11 standard-compliant security support (WPA, WPA2-PSK, WPA2-EAP, WPA3, PMF, WPA3-EAP).
Accelerators On-chip cryptographic engine (HW accelerator) to offload data encryption/decryption.
TI root-of-trust public key

The hardware-based mechanism that allows authenticating Texas Instruments as the genuine origin of certain content (such as firmware binary, RAM bootloader binary or other containers) using asymmetric keys.
Secure boot Validate the integrity and authenticity of the runtime binary during boot to verify that the downloaded firmware is signed by Texas Instruments and has not been tampered with.
Secured host interface Prevent physically sniffing SDIO/SPI to maintain data integrity.
Rollback protection Built-in HW mechanism to make sure that earlier versions of firmware cannot be reinstalled and used maliciously.
