iWave Systems Intros Security Suite for NXP i.MX to Secure Connected Devices

Article By : iWave Systems

iWave Systems' Security suite secures connected devices, enabling them with security functions such as encryption, storage, data transmission and certificate management.

With the rise of connected devices and the potential of exposure to large attack surfaces through various wireless technologies, there is now a great need to implement security by design in embedded connected products. Devices connected to a digital network can be subject to an attack; iWave introduced its Security Suite to protect billions of connected IoT devices.

The iWave Security Suite is developed for NXP’s i.MX 6 series, i.MX 8, i.MX 8X, and i.MX 8M application processors. With these processors built for numerous IoT and automotive applications such as gateways, multiple display applications, industrial systems, telematics units, and V2X solutions, there is a need to build a secure environment around the processors.

The iWave Security Suite helps secure connected devices, enabling them with security functions such as encryption, storage, data transmission, and certificate management. The easy-to-integrate solution helps address security challenges, creating a safe and secure environment. The iWave Security Suite includes secure boot, Wi-Fi secure API, event logging, OS hardening, access control, software firewall, and secure firmware updates.

i.MX 8 and i.MX 8X family application processors feature Advanced High Assurance Boot (AHAB) and a Security Controller (SECO), while the i.MX 6 and i.MX 8M applications processors features High Assurance Boot (HAB).

In i.MX 6, HABv4 enables ROM to authenticate the Bootloader and kernel image. In i.MX 8 and i.MX 8X family, AHAB enables SECO APIs to authenticate System Controller Unit (SCU) FW, SECO FW, Bootloader and kernel images which establish a chain of trust for the remaining software components by establishing a secure state of the system. The scripts provided by iWave along with the NXP Code Signing Tool (CST) makes the signing process extremely easy and simple.

Secure File System takes an end-to-end approach of protecting data by cryptography preventing unauthorized access to the data storage. Without proper encryption keys, data stored on any encrypted file system cannot be read (decrypted) with an entire secure storage partition encrypted and the root file system will be loaded.

Secure storage involves protecting data stored in storage devices like eMMC, MicroSD, and many more. The Security Suite facilitates secure storage APIs to encrypt and decrypt the storage device partition on runtime, data integrity, and data encryption. Secure storage APIs use Cryptographic Accelerator and Assurance Module (CAAM) black keys to store the key in the CAAM blob format so that data/key is secured in non-volatile storage device across power cycles.

The Security Suite supports robust, easy-to-use APIs to integrate with third-party applications and devices. The suite encompasses a compact package with a multi-level security solution.
