Embedded systems are the driving force for technological development in many domains such as automation products, industrial monitoring, control systems, automotive, and many more. As the number of connected devices continues to grow, this, in turn, has also led to tremendous cyberattacks worldwide.
Attacks could be focused on obtaining data for later use, or on compromising the functionality of a system to inflict damage directly. Each type of attack will focus on different components of the overall system. These attacks can damage our infrastructure, systems, and way of life. One of the major issues in IoT security is the lack of security in the IoT devices themselves.
The challenges in embedded system security:
Software running on the device can be easily attacked by hackers where they can modify the software and cause a security breach. Cryptographically signed code along with hardware support to verify code is authenticated to ensures software has not been tampered.
Privacy of data is the main concern when all devices are connected to the internet and are prone to remote attacks. Data security ensures data confidentiality though encrypted data storage and/or encrypted communication.
Connected devices are vulnerable to attacks, the first requirement you might think of is to have a secured method of communicating with devices. Proper authentication is needed to ensure that only authorized personnel can log in.
The best way to overcome unauthorized device production is to include security into the hardware, which ensures that the device is running authentic code. Hence device manufacturers need to ensure that devices are designed with security in mind, not just consider security as an afterthought.
A method of secure code updates ensures that the code on the device can be updated for security patches. Use of signed code (secure boot) ensures that malicious code cannot be introduced into the system.
iWave Security Suite Architecture:
Security suite secures connected devices, enabling them with security functions such as encryption, storage, data transmission, and certificate management. The easy-to-integrate solution helps address the security challenges creating a safe and secure environment. iWave’s security suite provides end-to-end security and prevents the information/data in the system from being hacked. Security Suite includes secure boot, Wi-Fi secure API, event logging, OS hardening, access control, software firewall, and secure firmware update to name a few.
Security Suite development kit:
iWave offers a Security Suite development kit, which is developed for different variants of NXP i.MX 8 and i.MX 6 high-performance applications processors. The development kit includes a software kit to help customers learn about and quickly implement Security Suite into their products.
Supported hardware development platforms:
Following are the Security Suite packages:
This package allows customers to evaluate the secure boot and secure storage features in i.MX 8M Mini and i.MX 8 QM platforms.
There are lot more precautions to be taken care of when fusing the keys to the board and signing the binaries. iWave offers OTP fusing API and Signing Tool which do the work in just one step.
iWave offers a secure storage API and Data encryption-decryption API to encrypt the block of storage or the piece of sensitive information.
With an attacker having enough time, resources, and motivation to always break into any system, there is no guarantee for security. For this reason, iWave provides Security solutions to products to protect against specific threats trying to achieve a balance between the cost of security implementation and the benefits obtained.
