\textbf{Bluetooth LE} relies on spread-spectrum security, however it is trivial to recover follow frequency hops rendering BLE insecure (Ryan, 2013).  \textbf{6LoWPAN} employs dual strategy - 128-bit AES in the link layer and well known TLS from RFC 5246.  \textbf{Narrowband-IoT} security features are not specified as of June 2016. Company Ericsson in their whitepaper (Cellular networks for massive IoT) states that security measures will be similar to current offerings in mobile networks.
