At embedded world 2015, Infineon presented a device identity management solution for smart home applications. iBadge is a plug and play solution for secure connection of devices in the IoT. Thanks to iBadge, users can comfortably and securely access home networks via smartphone apps and cloud-based services to remotely switch on heating on the way home or access video surveillance while travelling.

In the IoT, device identification and management is essential to counteract security threats that arise from the use of fake servers or fake devices. To prevent threats, mobile devices, smart cars and even home appliances must be securely identified before being granted access to a connected system. The Infineon OPTIGA Trust authentication chip is at the core of the iBadge solution. When integrated into smart heating or lighting systems or surveillance cameras, this security chip is used to authenticate those devices that are authorised to access the network.

According to market analyst firm Gartner 2.9Bn connected things will be in use in the consumer sector in 2015 and will increase to over 13Bn devices in 2020.

Compared to solutions available today, iBadge makes device identity management more secure and easier while reducing manual work during the production process. The iBadge evaluation board is provided with an IoT System in Package (SiP) including the MCU, a wireless module, a host interface and the OPTIGA Trust authentication chip. Therefore, the solution allows IoT device makers as well as traditional home electronics makers to quickly integrate iBadge into their devices.

The Infineon OPTIGA Trust authentication chip in the iBadge solution provides a unique chip ID, strong asymmetric authentication (ECC-163), session keys for each application and a dedicated ODC-OPTIGA Trust Digital Certificate. The unique identifier and cryptographic keys are stored on the chip during a highly secured and certified production process.

“Thanks to our in-depth system understanding and our tailor-made security products we have enabled our partners to design a plug and play solution for smart home applications,“ said Juergen Spaenkuch, Head of Platform Security, Infineon. “The ‘iBadge’ solution is also a perfect example for Infineon’s Product-to-System approach which benefits both our customers as well as users who now have a comfortable and secured smart home solution at hand.”

iBadge was designed and developed by Taiwan-based embedded security company IKV-Tech in close cooperation with Teamsourcing, an App and Cloud Services Provider, and the chip provider AcSiP specialised on SiP solutions. Evaluation Boards are available upon request.
