Security Required for IoT Devices Connected to the Cloud
With the rapid progress of IoT, the cybersecurity risks of IoT devices are also increasing proportionately. Even at development sites, there is an increasing number of cases, both inside and outside the company, that consider security measures when connecting devices to the cloud. However, since the field of device security is highly specialized, it is likely that companies have not yet established effective measures for their own devices and how to implement them.
Challenges in connecting IoT devices to the cloud
There are two major issues that must be paid attention to when connecting IoT devices to the cloud.
- Ensuring a means of establishing secure communication with the cloud through mutual authentication
- Investigation of means to safely store and manage various electronic certificates required for mutual authentication in IoT devices
The solution is Infineon's OPTIGA™ Trust M
- You can pre-write the electronic certificate according to the cloud service you are using.
- By writing an electronic certificate to Trust M, which has tamper resistance, the certificate can be stored securely.
