The Internet of Things (IoT) is a growing technology that continues to gain traction year after year. On the one hand, it can be helpful, but on the other hand, it carries many security threats. These threats include scalable remote attacks, side-channel attacks on cryptography, DDoS attacks, data breaches, malware, and others. By Roland Atoui.
The article then search answer for the following questions:
- Why use Quantum Cryptography?
- Why secure IoT?
- How does Quantum Cryptography work?
Of course, technical quantum solutions are challenging to implement in IoT devices due to technical and commercial constraints. Therefore, a few security options combine both the quantum and classical approaches. One option keeps the current semiconductor chips but uses quantum techniques to create a unique long cryptographic key for every device. This can be done with a quantum random number generation (QRNG). It creates a noise source with a high randomness level.
Although quantum cryptography and quantum computing have developed quite efficiently, some more advancement is necessary for them to become a reality in commercial systems. Commercial use is a big challenge. Firstly, implementing quantum systems in IoT is expensive. Secondly, large-scale quantum apparatus is hard to afford for many organizations. Thirdly, the properties of photons restrict them from traveling long distances. If these issues can be resolved, we will have successful IoT systems with quantum cryptography. Good read!
