Internet of Things Connectivity
As the Internet of Things (IoT) grows, the challenge and opportunity for telecoms operators is to manage millions of interactions between sensors and devices, whilst securing the sensitive information that is being transmitted and captured. When considering the number of smart home devices which now appear in our households as an example, the high level of personal data which could be exposed through a failure in an IoT system can be understood.
Data and network security is a costly and essential part of IoT connectivity. The failures in IoT security currently involve devices that verify, connect or spend improperly with other devices. For years, researchers have demonstrated the ability for hackers to compromise such devices in order to control implanted cardiac devices, disable cars remotely and bring websites to a grinding halt by launching huge Distributed Denial of Service (DDoS) attacks.
By placing barriers in front of attacks from hackers, blockchain offers an additional layer of security that is underpinned by some of the most robust encryption standards available. This enables secure and error free peer-to-peer connectivity for thousands of IoT devices with cost-efficient and self-managed networks.
Blockchain can serve as a tool to both log data in a form highly resistant to tampering, and to fight the introduction of malicious IoT devices (via inexpensive networked devices with little or no native security features) into our networks. By registering an IoT device on blockchain, other devices on the network will know with a high degree of confidence that a device is what it says it is.
