IoT security for IoT devices

IoT security on the highest level for enterprise and consumer IoT

With every new application of the IoT, device manufacturers and other IoT companies are expected to deliver new and innovative services with better, faster, and sleeker features. And, does it need to be repeated? At the same time, increasingly complex security requirements need to be met. The Internet of Things (IoT) is becoming more present in our daily lives. New applications and developments such as smart cities, autonomous cars, Industrial networks, and Products-as-a-Service (PaaS) capture our attention today. Everywhere, sensors and remote-controlled systems are becoming standard. Ensuring the security of the data transfer is essential, even business critical. All of this is apparent. But the demands on the IoT are often inherently contradictory.

In addition to the call for security, fierce price competition drives the optimization of processes and costs. A seamlessly simple customer experience belies the need for a complex security solution. Secure and convenient-to-use connected devices are indispensable to nurturing consumer trust. Data-sensitive services, such as payment, identification, access, and transport, are essential. Robust, easy-to-manage device security that enriches the customer experience is a strong selling point that can be leveraged to differentiate oneself from the competition. 

Mobile operators can securely manage the lifecycle of cellular subscriptions with our proven and future-proof eSIM Management solution that addresses the consumer, enterprise, and IoT markets. But don’t just take our word for it. Our innovative solutions are regularly awarded by renowned IoT security experts. 

Sustainability requires trust. For a sustainable IoT, we need to ensure that connected devices and the data they transmit can be trusted.

Empowering IoT security with SIM-based services

The IoT differs according to whether the application is for a consumer or enterprise environment. User-centric consumer applications focus mainly on connected devices with an interface, such as tablets or smartphones. Enterprise IoT applications, on the other hand, run on devices that for the most part are headless, that is, have no monitor or other user interface. They are designed to be data-centric, such as sensors.

Mobile operator SIMs, used to authenticate phones, also enhance IoT security. A SIM serves as a secure root of trust, provisioning and storing digital certificates and credentials. This enables robust device identification, secure server interaction, and data encryption. Existing provisioning infrastructure can be used for cost-effective, safe credential updates on SIMs. Over-the-air additions, including PKI certificates, maintain device identity securely throughout its life.

We offer various SIM-based applications that enhance the security and functionality of IoT use cases and help protect devices and data. Its core services are IoT SAFE, Zero Touch Provisioning, IoT Protect, and SIGNiT®. The platform covers both the backend and SIM software. It enables mobile operators to offer a consolidated toolbox to OEMs and enterprises. They, in turn, are able to manage SIMs and other devices over the entire lifecycle – from manufacturing and activation, to managing subscriptions and policies, all the way to deactivation.

IoT SAFE

Companies build IoT solutions for the marketplace, and these devices connect to cloud platforms. The credentials, however, are mostly stored within the application processor memory. This makes them an easy target for attacks. Our IoT SAFE protects against threats and provides cybersecurity by adding a secure element (a SIM card, eSIM or iSIM) to the IoT device. It is equipped with an applet that assists with the authentication to the cloud provider. 

In addition, our offering includes a credential manager that controls and replaces factory credentials. We also offer a device toolkit that provides documentation, which includes the sample code that is used to assist the IoT device developer in securing the communication between the IoT device app and the SIM applet. 

Zero Touch Provisioning (ZTP)

For businesses with large fleets of IoT devices in the field, getting these devices up and running can involve a lot of time, effort, and cost. Zero Touch Provisioning is a SIM-based application, for quick, simple device onboarding with no device or platform dependencies.   

This innovative tool uses the SIM to negotiate a trusted connection with your API upon first network registration. The ZTP application also requests the device to report its identification, while the location is obtained from the network registration info. This info can be used to provision device settings when the device is switched on.   

This enables quick scaling of device deployments and reduces device manufacturing costs as security functions are shifted to the SIM. Large numbers of devices can therefore be deployed simultaneously, enabling organizations to scale their IoT deployments quickly and efficiently.

IoT Protect

The overall functionality of IoT Protect is to provide an end-to-end encryption/decryption mechanism for IoT applications. Information is transmitted securely between the IoT device and the backend, independent of the communication channel (broadband, NB-IoT, Wi-Fi, etc.). Common applications for IoT Protect are those in which the volume of data transferred is low, which is typical for low-end and battery-powered IoT devices.

Badge from Juniper Research, Award for Best IoT Security Platform

Juniper Research recognizes G+D’s IoT Protect as a great tool for operators to enable SIM management and IoT lifecycles. The enhanced security for devices in IoT networks is enabled by cryptographic processes of its IoT Protect service. It provides significant protection for IoT applications that can be targets for attacks.

SIGNiT®

SIGNiT® ensures data integrity in multi-party IoT ecosystems by signing every IoT data packet at the source, the sensor, using digital signatures from SIM,eSIM or iSIM. It's an award-winning solution, recognized by Juniper Research for blending secure SIM environments with blockchain technology, facilitating secure, decentralized processes for IoT data. 

Commercially proven, it's set to impact diverse sectors, like logistics, agriculture, energy, and automotive. For instance, Lufthansa Industry Solutions relies on SIGNiT® for 100% trustworthy IoT data, incorporating G+D's security tech and a pioneering Ubirch blockchain. This unique combination secures sensor data in an immutable blockchain, setting new standards.

Juniper Research: Platinum Winner, Best Mobile Identity Solution, Telco Innovation Awards 2022

Juniper Research has awarded SIGNiT® from G+D as an innovative solution to combine secure and proven SIM environments with blockchain technology. It allows to easily digitalize and secure processes in a decentralized ecosystem while providing IoT users with comprehensive and robust security for data generated by IoT devices. The solution has already been successfully implemented in commercial environments, and Juniper Research expects SIGNiT® to have further positive impacts in other IoT sectors, such as logistics, agriculture, energy and the automotive industry.
