IoTree: TLS encryption for NB-IoT
NB-IoT is an LPWAN radio technology standard developed to enable a wide range of IoT applications. NB-IoT is particularly focused on indoor coverage, with low cost, long battery life and high connection density. TLS over NB-IoT is a simple software extension that on the one hand fixes known vulnerabilities and on the other hand provides WAN-enabled end-to-end security according to TR-03116–3 and thus meets the requirements of the IT security catalog of the Bundesnetzargentur according to [§11 Abs. 1a EnWG].
With NB-IoT The Name Says It All
Narrowband IoT is a radio standard that is explicitly intended for applications in the Internet of Things area. Existing mobile radio networks are used, which is especially advantageous for remote or scattered locations. NB-IoT can be used as an alternative to LoRaWAN and brings its own advantages:
- No own communication network is required
- Low power consumption due to low data rates (up to 230 kBits/s) at a bandwidth of 180 kHz
- Higher building coverage than LTE
NB-IoT Requires Additional Security
When using NB-IoT, the data to be transmitted is encrypted and sent to the network provider. There the data is decrypted and transmitted to the user’s destination server. The UDP protocol is often used, which corresponds to an unencrypted connection. Attackers could thus permanently disrupt the connection and decrypt or even manipulate the transmitted data. The BSI therefore prefers TLS encryption when using WAN connections in accordance to TR-03116–3. Security must not be neglected, especially when dealing with sensitive company data, personal data, as well as for use in critical infrastructures.
PHYSEC Offers BSI Compliant Security
Our security solution for NB-IoT provides additional end-to-end TLS encryption. This enables us to provide secure connectivity from the field component to the ERP system or IoT platform. We thus combine the advantages of NB-IoT with the high security requirements of the BSI. Our solution is suitable for all applications requiring high data security and was developed from the user perspective for smart metering, smart grid and critical-infrastructure-applications in cooperation with the Stadtwerke Bochum.
This is How Our Technology Works
The additional TLS security layer is applied to the NB-IoT protocol without changing it. Thus the system is 100% NB-IoT compliant. The security technology used is fully mature and uses established crypto standards.
There are no special infrastructure requirements for using encryption and platform integration. Any NB-IoT network can be used. There is no necessity to change the hardware.
The Result: Maximum Security!
- TLS encryption protects the confidentiality and authenticity of your sensor and actuator data.
- The mature technology enables you to achieve a high level of security by using established crypto standards.
- Due to constant further developments and updates, your network will remain secure in the future.
- Terminal device and server software verify their mutual identity with certificates.
- You retain data sovereignty — neither end device nor software manufacturers manage key material.
