What security features does NB-IoT provide?


  • NB-IoT provides security features based on known LTE technology. The security features cover three categories:

    • Confidentiality: The customer payload is encrypted between NB-IoT modem and Cellular IoT Serving Gateway Node (CSGN). Between the private APN and server, the traffic is protected using IPSec (device cannot be accessed from the Internet).
    • Integrity & authentication: The NB-IoT device authenticates itself at the network, based on known LTE registration procedures (SIM based authentication)
    • Availability: If a redundant APN has been ordered the APN is distributed across two geo-redundant CSGNs.
