The security concept
NB IoT is part of the mobile network, fully managed with standardized security to guarantee the
credential and integrity of all data running through it. NB IoT has passed security protocols as
outlined by 3GPP, the organisation responsible for managing the mobile network.
The NB IoT module chipset included in our NB IoT smart locks applies 2048 bit RSA encryption
All communications are running on HTTPs 128 bit military grade encryption between all the
vertical applications including software and hardware. Between the telco's mobile network, and
the IoT device management platform a layer of Internet Protocol Security (IPSEC) is provided.
The Telecommunication company on some occasions, also provides a dedicated VPN for
further security and reliability.
