Abstract
A method performed by one or more network node(s) of a wireless telecommunications network to dynamically manage encryption keys for multiple narrowband Internet of Things (NB-IoT) devices of the network. The network node(s) can maintain a database that stores a device profile for each of the NB-IoT devices and obtain multiple encryption keys for the multiple NB-IoT devices. The encryption keys are associated with different encryption strengths ranging from high to ultra-low encryption strengths. The network node(s) can allocate the encryption keys to the NB-IoT devices, detect a change in the condition of the network, capability or communications service of NB-IoT devices, and refresh the encryption keys accordingly to ensure that the network nodes properly balance encryption while providing efficient network performance.
