Digital Communication & End-to-end Encryption

Secure IoT Communication

Enabling Internet of Things (IoT) use cases is a top topic of priority for network operators worldwide. Therefore, the baseline for IoT use cases across all industries is the reliable security of the communication between the IoT endpoints and devices over networks.

The number of active IoT device connections worldwide is already around 14 billion. This figure is expected to double by 2030 - rising sharply in the coming years, showing the rapid change toward fully connected IoT environments (see here for further details).

With the number of connected endpoints and devices, the amount of data exchanged over mobile or local telecommunication networks also increases. If not adequately protected, each connected endpoint could be a potential loophole for unauthorized access. Furthermore, the data transferred also carries a risk for breaches - in particular, for IoT communication within critical infrastructures such as Healthcare, Emergency Services, Government, Energy and Utilities.

A proactive approach to securing communication between internet-enabled devices requires multiple tiers of protection. This means that effective security of the whole IoT communication environment is essential to secure IoT connections and applications.

Utimaco provides the appropriate applications for all use cases in each industry.
