NB IoT SECURITY
By Steve Dunn May 2020
Unlike some forms of connectivity, NB IoT networks are carefully managed and secured by mobile operators. As such, the growing usage of NB-IoT will help to counter security threats to the IoT, such as the hijacking of devices by botnets and the hacking of sensitive data belonging to individuals or organisations.
By supporting an array of security features and safeguards, NB IoT networks are set to play a pivotal role in building trust in the Internet of Things, while giving enterprises the confidence they need to bring mission-critical assets online, so they can be remotely monitored and controlled.
Telco's guarantee that the device that sends data to the cloud is authorized and no one has replaced it with another. Telco's also guarantee that a communications observer cannot understand the messages and only the cloud with the decryption keys can retrieve the messages. Finally Telco's guarantee that no one has altered the message that the IoT device sends to the cloud.
NB IoT smartlocks have unprecedented encryption - Military grade 256 bit encryption is running on all the vertical layers between software and hardware, plus 2048 bit NB IoT chipset encryption. HTTP military encryption - All communications are running on HTTPs military grade 128 bit 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 provides a dedicated VPN for further security and reliability
NB IoT is the only licenced IoT technology - all other machine to machine communication technologies are unlicensed, unregulated, uncontrolled and insecure. NB IoT has passed security protocols as outlined by 3GPP/GSMA, the organisation responsible for managing the mobile network
NB IoT operates on the telco's mobile networks, and they've spent over 30 years and billions of dollars perfecting their network security. And as NB IoT is part of the mobile network, it is fully managed with standardized security to guarantee the credential and integrity of all data running through it
All other electronic locking technologies have been hacked, so NB IoT is what locks need right now. For example In 2017, RFID keycards, commonly used in offices and hotels, were shown to be easily copied at a DEFCON conference using a device costing $20. In 2019 hackers sent a command to tell a Wi-Fi lock to open or close with just a few lines of code, connected to a vulnerable Wi-Fi smart hub. Back in 2012, over 4 million magnetic stripe locks in hotel rooms, were shown to be hackable, and easily opened with a device that costs less than $20.
