LoRaWan is a wireless network standard that uses low-cost radio spectrum to connect devices. It’s designed to be secure and provide long-range connectivity, even in areas where cellular networks don’t work well. The IETF has defined three critical components of LoRaWan security:
LoRaWAN Messages can be encrypted.
To encrypt a message, the LoRa gateway uses a secure element to store security keys and perform cryptographic operations. The devices communicate using this encryption key during the initial authentication process. After authentication, the device will only send encrypted data if it has received an appropriate acknowledgment from its network partner (Gateway). To authenticate your LoRa Gateway, you’ll need to use an application system on your smartphone or tablet that will validate the Gateway on authentication.
Use a Secure Element to store security keys and perform cryptographic operations.
You can store security keys and perform cryptographic operations using a secure element. The interface between your LoRa Gateway and the particular Element is a critical public infrastructure (PKI) protocol that allows you to authenticate users, hold their credentials securely in memory, protect data from tampering, and more. Secure elements are tamper-resistant devices that contain both hardware and software components. They’re used in payment cards, passports, credit cards—you name it!
Trust Check: An embedded application system (Secure Element) will validate the Gateway on authentication. Secure Element is a tamper-resistant hardware device that stores security keys and performs cryptographic operations. It protects the Gateway from outside threats, such as hackers and other malicious users.
The Secure Element is embedded in the LoRa Gateway itself so that it will communicate with your LoRaWan Gateway via Bluetooth low energy (BLE). The BLE interface allows you to access information about your Gateway without physical access, making it more secure than using wifi or wireless connections directly between devices like smartphones or tablets.
This feature also makes it possible for any application on your phone or PC/Mac computer connected via USB cable to access data stored within its secure Element over wifi when needed – this could include things like live temperature readings from sensors inside homes where there isn’t any power available!
If you are concerned with LoraWan security, use a secure element to protect your LoraWan gateways.
Secure elements are tamper-resistant and hardened against physical attacks. They also help prevent side-channel attacks by using cryptographic techniques that make it impossible for an attacker to determine information about the device’s inner workings by observing its behavior on the network or in its memory without being noticed by other devices. In addition, they can be used as part of a software firewall or intrusion detection system (IDS) that monitors traffic entering or leaving their networks and takes action when suspicious activity occurs (e.g., shutting down the port).
How is a LoRa gateway operated?
Radio modules known as LoRa gateways are equipped with a LoRa concentrator, which enables the reception of LoRa packets. In the LoRa gateway’s operating system background, packet forwarding software operates. The network administrator has more control over how to manage his gateway in this fashion. Although the data rate between the end node (also known as the node or end device) and the LoRa gateway is rather low, this compromise is required to support long-lasting battery life and a wide radio spectrum. Modules whose devices include a LoRa concentrator that enables the reception of LoRa packets.
In summary,
LoRaWan is a secure protocol with robust security features. It provides encryption for all its messages and has a trust check to ensure the gateways are authenticated before allowing them to connect. You can use a secure element to store security keys and perform cryptographic operations on your LoRaWan devices. Also, it’s essential not only that you protect your message but also to make sure they’re not being monitored by someone else without authorization.
